摘要： Apparatuses, systems and methods for transmitting and receiving modulated impulse radio signals. An impulse radio receiver includes a time base, a precision timing generator, a template generator, a delay, first and second correlators, a data detector and a time base adjustor. The time base produces a periodic timing signal that is used by the precision timing generator to produce a timing trigger signal. The template generator uses the timing trigger signal to produce a template signal. A delay receives the template signal and outputs a delayed template signal. When an impulse radio signal is received, the first correlator correlates the received impulse radio signal with the template signal to produce a first correlator output signal, and the second correlator correlates the received impulse radio signal with the delayed template signal to produce a second correlator output signal. The data detector produces a data signal based on at least the first correlator output signal. The time base adjustor produces a time base adjustment signal based on at least the second correlator output signal. The time base adjustment signal is used to synchronize the time base with the received impulse radio signal.

摘要： A communication system in which circuits for generating transmitting-end synchronizing signals and receiving-end synchronizing signals can be realized easily even in the case of a data transmission rate being high and in which power consumption is low. A transmitting-end synchronizing signal selector in a transmitter selects one of a plurality of transmitting-end synchronizing signals with different phases outputted from a transmitting-end synchronizing signal generator on the basis of code-spread data to be transmitted. A transmitting-end signal output unit outputs a radio signal in synchronization with the selected transmitting-end synchronizing signal. A receiving-end synchronizing signal selector in a receiver selects one of a plurality of receiving-end synchronizing signals which are outputted from a receiving-end synchronizing signal generator and which are the same as the plurality of transmitting-end synchronizing signals on the basis of a despreading code. A receiving-end signal output unit outputs a correlation-detected signal which is synchronized with the selected receiving-end synchronizing signal and with which the correlation of the radio signal is detected. A correlator detects a correlation between the radio signal transmitted from the transmitter and the correlation-detected signal.

The data pulses and the cyclic signal may be modulated by varying a phase of the data pulses and cyclic signal. The phase shifted data pulse may be used to generate an ultra-wideband pulse for transmission. The modulated data pulses and cyclic signal may be gated such that the data pulse and only a monopulse of the cyclic signal pass through the logic gate.

摘要： A method for reference signal generating in an ultra wideband (UWB) communication system which sends out and receives data by using at least two reference signals of predetermined frequencies. A first signal group, which comprises a local oscillation (LO) signal and a signal at a predetermined phase difference with respect to the LO signal, is generated. One among at least two intermediate frequency (IF) signals is selected for the adjustment of the frequency of the LO signals, and a second signal group, which comprises the selected IF signal and a signal at a predetermined phase difference with respect to the selected IF signal, is generated. Two mixed signals are generated from the first and the second signal groups, the mixed signals being mixed without overlap, and a reference signal is generated by adding the two generated signals.

摘要： An RF transmitter includes a reference signal generator, a signal generator, and a mixer. The reference signal generator provides a reference signal that has a prescribed or desired frequency. The signal generator provides an operating signal in response to a selection signal. The operating signal has a frequency that equals the frequency of the reference signal multiplied by a number. The mixer mixes the operating signal with another signal to generate a transmission signal. An RF receiver includes a first mixer, a second mixer, an integrator/sampler, and a signal generator. The first mixer receives as its inputs an input RF signal and a second input signal, and mixes its input signals to generate a mixed signal. The integrator/sampler receives the mixed signal and processes it to provide an output signal. The signal generator provides an operating signal in response to a selection signal. The operating signal has a frequency equal to the frequency of a reference signal, multiplied by a number. The second mixer mixes the operating signal with a template signal to generate the second input signal of the first mixer.

摘要： System and method for analog signal generation and manipulation in an ultra-wideband (UWB) transmitter. A preferred embodiment comprises a digital portion 305 of an UWB transmitter (for example, transmitter 300), which is responsible for encoding a data stream to be transmitted, and an analog portion 330. The analog portion 330 creates a stream of short duration pulses from the encoded data stream and then filters the stream of short duration pulses. To simplify the generation of the short duration pulses, a quantized representation of the short duration pulse is used. The quantized representation is created via the use of control signals that by coupling differential amplifiers together (such as amplifier 611), generate a voltage drop across a resistor (such as resistor 619) and hence, a current.
