摘要： Improved radio receiver designs are disclosed that can be used in the operational environment of wireless communications. The radio receiver includes a signal input terminal, a variable-current RF signal amplifier, a demodulator, and a controller. The variable-current RF signal amplifier has an input terminal for accepting RF input signals, an output terminal for generating an amplified version of the RF input signals, and a current control terminal for controlling the current consumption of the RF signal amplifier. The signal input terminal is coupled to the input terminal of the variable-current RF signal amplifier, the output terminal of the variable-current RF signal amplifier is coupled to the demodulator, and the current control terminal is coupled to the controller. The controller is also coupled to the demodulator. A received signal, including any noise and/or interference, is coupled to the signal input terminal. In response to signals amplified by the RF signal amplifier and demodulated by the demodulator, the controller controls the current consumed by the variable-current RF signal amplifier. The controller adjusts the current consumed by the RF signal amplifier to achieve at least a minimum acceptable signal-to-interference ratio for a desired signal, while the Noise Figure is not degraded any more than is necessary to achieve a minimum acceptable signal-to-interference ratio at any given time. In this manner, the variable current RF signal amplifier is adjusted to obtain a required amount of intermodulation performance for a given set of receiving conditions. This technique saves operating current and maintains fade margins because, in practice, interference conditions do not persist all of the time, and are usually of temporary duration.

摘要： Improved radio receiver designs can be used in the operational environment of wireless telephone communications. The radio receiver includes a variable attenuator, a variable-current RF signal amplifier, and a controller. The controller controls the amount of attenuation provided by the variable attenuator, and/or the current consumed by the variable-current RF signal amplifier, in response to signals received by the RF signal amplifier. The controller adjusts the variable attenuator, and/or the RF signal amplifier, to achieve a minimum symbol error rate and/or to maximize the signal-to-noise and interference ratio for a desired signal, irrespective of the levels of any interfering signals received by the RF signal amplifier. In this manner, the variable attenuator, and/or the variable current RF signal amplifier, are adjusted to obtain just the right amount of intermodulation performance for a given set of receiving conditions. This technique saves operating current and minimizes noise figure because, in practice, interference conditions do not persist all of the time, and are usually of temporary duration.

摘要： A wireless telemetry system includes many radio transmitters using frequency-hopping carriers for intermittently transmitting very short messages indicative of status of stimuli associated with the transmitters. The transmitters can transmit independently of any receiver for receiving from the transmitters and independently of each other. Transmission frequency and time between transmissions are varied according to time-frequency patterns that can be different for each transmitter. Urgent messages, such as alarms, are transmitted at transmission opportunities at intervals smaller than routine transmissions. The transmission opportunities are also according to a time-frequency pattern. Power-up transmissions carry information about future transmission opportunities and/or routine transmissions. Power-up transmissions can also carry information about time-frequency pattern for controlling routine transmissions and/or transmission opportunities. The system comprises a receiver for receiving from the transmitters. The receiver holds data indicative of time and frequency of future routine transmissions and transmission opportunities simultaneously for each of the transmitters.

摘要： A Multi-Code (MC) Code Division Multiple Access (CDMA) receiver receives N (where N>1) encoded signal channels over multiple air signal paths. The MC-CDMA receiver receives and demodulates the N encoded signal channels into N signal samples and includes a common circuit for time-sharing an accumulator, for accumulating the N signal samples, among a plurality of second correlators. Each of the plurality of second correlator means utilizes the time-shared accumulator to accumulate samples from each of the N signals which are then decoded into an associated one of the N signal channels.

摘要： An improved control voltage generator for use with a voltage-controlled oscillator (VCO), so as to enable VCO operation at low supply voltages of less than three volts. The control voltage generator includes a phase comparator, a charge pump, a switched voltage multiplier, and a control voltage filter. The output voltage of the phase detector is coupled to a sampling terminal of the charge pump, a power supply terminal of the charge pump is coupled to an output terminal of the switched voltage multiplier, and a voltage input terminal of the switched voltage multiplier is coupled to a first, reference signal. The charge pump, powered from the power supply terminal, generates a waveform including a plurality of pulses. Each of the plurality of pulses has a time duration substantially proportional to the voltage present at the sampling terminal. These pulses may be used as a VCO control voltage or, alternatively, a control voltage filter, coupled to the charge pump, may be used to transform the pulses into a VCO control voltage having desired characteristics.

摘要： A spread spectrum communication system for direct sequence transmission of digital information having a modulation format which is particularly suitable for indoor communication within residential, office and industrial structures. The modulation format combines BPSK or MSK spreading with FM carrier modulation by data bits and a carrier frequency shift whose magnitude is related to both a chip rate and a spreading sequence length. The carrier, chip clock and data clock are all synchronous and the sequence length is an integral submultiple of the bit length. The system reduces the frequency error between the transmitter chip clock and the receiver chip clock to permit the elimination of a code phase tracking loop in the receiver to reduce the receiver complexity. The receiver has an extended dynamic range which makes possible the reception of very strong signal without an automatic gain control loop (AGC) as well as reducing the time needed for code phase acquisition. The transmission system is highly resistant to CW jamming and short distance multipath effects.

摘要： Contamination in a feedback signal is eliminated in a laser scanning arrangement having a drive coil driven by a drive signal formed as a periodic train of drive pulses to oscillate a scan mirror and a light beam reflected from the scan mirror. A feedback coil generates a feedback signal during oscillation of the scan mirror, the feedback coil being in proximity with the drive coil and being subject to corruption by cross-coupling between the coils. The drive coil is not driven with at least one drive pulse during a quiet time period. Cross-coupling is eliminated by generating the feedback signal only during the quiet time period, and by monitoring a position of the scan mirror by processing the feedback signal which was generated only during the quiet time period.

The transmitters transmit transmissions independently of a receiver receiving the transmissions and independent of each other. In operation, radio transmitters transmit messages at varying frequencies at time intervals that can be varied as well. The frequency and time intervals are varied according to patterns that can be determined individually for each transmitter. A receiver holds data indicative of the future transmission frequency and time for each transmitter and updates the data based on the time and the content of the received messages.

摘要： A telemetry system includes many radio transmitters using frequency hopping carriers to intermittently transmit transmissions indicative of status of sensors associated with the transmitters. The transmitters transmit transmissions independently of a receiver receiving the transmissions and independently of each other. The carrier frequency and the time between transmissions are changed according to a frequency-time hopping sequence that is different for each transmitter. The sequences and the resulting frequency ad time hopping are predictable and can be reproduced in the receiver based on the transmitter ID number. The system also includes one or more receivers containing a plurality of memory registers to hold, simultaneously for each transmitter, digital data indicative of (a) expected time and (b) expected frequency of the next transmission occurrence. The data is updated based on the time and the content of the received transmissions. The receiver authenticates the received transmissions by discriminating transmissions received at a wrong frequency and time. In addition, each transmitter encrypts the transmission using a variable encryption key that is varied with each transmission. The key variations are based on the frequency and time hopping sequence and are different for each transmitter. Alternatively, prior to encryption, each transmitter modifies data for transmission, using a modifier that is varied based on the frequency and time hopping sequence that is different for each transmitter. In addition, for faster acquisition and robust operation, the receiver includes and RSSI circuit based on FFT to detect transmitted carrier power at several different frequencies. The receiver also includes one or more frequency selective circuits that are tuned in response to the outputs from FFT and the status of the time and frequency registers.
