摘要： Levels of power reduction for signals to be transmitted from a mobile communications device via radio channels in a digital wireless communications system, where each signal is modulated according to one of a number of modulation configurations, are determined. For each modulation configuration a first estimate of a power reduction is calculated (101), and the calculated first estimates are storied (102) in the device. The method comprises the steps of determining (103) a limited set of modulation configurations, said limited set comprising modulation configurations that have been determined likely to be used in practice; calculating (104) for each modulation configuration of the limited set an optimized estimate of a power reduction; and storing (105) the calculated optimized estimates in the device. In this way the power consumption of the device is reduced while keeping a look-up table at a reasonable size.

摘要： In a multi-carrier wireless system, potential problems from reconfiguring mobile station resources to accommodate changes in component-carrier configuration are mitigated by inserting a guard period each time the configuration of component carriers changes, so that transceiver reconfiguration can be carried out without interfering with ongoing transmission. A base station is configured to transmit data to a mobile station according to a first configuration of two or more component carriers, to determine that a change of configuration to a second component-carrier configuration is required, and to signal the change of configuration to the mobile station, using the first configuration of component carriers. The base station then refrains from transmitting data to the mobile station during a pre-determined guard interval of at least one transmission-time interval subsequent to the signaling of the change of configuration. After the guard interval, data is transmitted to the mobile station according to the second component-carrier configuration.

摘要： A method and apparatus for controlling the power consumption of a receiver based on current operating conditions is described herein. A receiver according to the present invention applies a received signal to a variable filter. The received signal includes a desired in-band signal. Depending on the current operating conditions, the received signal may further include one or more unwanted out-of-band blocking signals. A filter controller controls one or more operating parameters of the variable filter to maintain the power ratio at the filter output of the power of the blocking signal(s) to the in-band signal at or below a desired level. In so doing, the present invention controls the receiver power consumption while still providing the desired receiver performance.

摘要： Coupler-based amplifiers provide a measure of load mismatch based on the difference between the two output signal amplitudes from the amplifiers. This measure can be used to control variable matching networks (VMNs) or amplifier supply voltages to maintain constant distortion levels and high power transfer/efficiency and even to control output power. Load mismatch is measured by comparing the amplifier device output amplitudes and adjusting the circuit based on the comparison to counteract undesired behavior, such as increasing distortion levels.

摘要： A beam forming receiver comprises a plurality of front end circuits (4, 5, 6, 7, 8) receiving RF signals from array antennas (2, 22) and down-converting them to analog baseband signals. A receiving section comprises a first beam former (11, 12, 13) that controls phase and amplitude of each analog baseband signal individually to obtain analog phase shifted signals and combines them to a combined analog baseband signal. A beam tracking section comprises analog-to-digital converters (35, 36) to convert the analog baseband signals to digital baseband signals, and a second beam former. The second beam former phase shifts and combines the digital baseband signals to a combined digital baseband signal; and the searching and tracking section can further determine from this signal a signal indicative of a beam direction and provide it as a control signal to the first beam former.

摘要： Interference cancellation techniques may be implemented in a radio transceiver configured to transmit a radio-frequency transmit signal at a transmit frequency and having two or more local oscillators operative to simultaneously generate local oscillator signals, at corresponding local oscillator frequencies, for simultaneously down-converting two or more corresponding received radio-frequency signals. An example method begins with identifying one or more self-interfering frequencies, based on the local oscillator frequencies and the transmit frequency. A baseband cancellation signal is then generated by weighting and frequency-shifting a baseband representation of the transmit signal, based on the identified self-interfering frequencies. The baseband cancellation signal is then combined with a down-converted received signal, to obtain an interference-reduced baseband signal.

摘要： An attenuator control method of a signal processing chain comprising two or more signal processing units is disclosed. One of the two or more signal processing units is a signal attenuator adapted to apply adaptive signal attenuation of an attenuator input signal based on one or more attenuation parameters to provide an attenuator output signal. At least one of the two or more signal processing units has an associated wearout process and a corresponding wearout budget, wherein a wearout event of the wearout process occurs when a level of a wearout indication signal of the signal processing chain is in a wearout region, and wherein the wearout process is modeled by a wearout event cost associated with a corresponding wearout event. The method comprises obtaining an indication of whether a wearout event of the wearout process has occurred. If the obtained indication shows that a wearout event of the wearout process has occurred, the method comprises updating a wearout accumulation metric of thewearout process by the associated wearout event cost, comparing the wearout accumulation metric of the wearout process with one or more wearout thresholds of the wearout process, and adapting the attenuation parameters of the signal attenuator based on the comparison.The method also comprises controlling the signal attenuator based on the attenuation parameters. Corresponding attenuator control arrangement is also disclosed.

摘要： In a dual-carrier, double-conversion Orthogonal Frequency Division Multiplexing (OFDM) receiver a frequency synthesizer generates a first local oscillator signal for the first down-conversions stage of the receiver. A frequency divider is used to derive a second local oscillator signal from the first local oscillator signal, thus eliminating the need for a separate frequency synthesizer for the second down-conversion stage. A controller determines the frequency of the first local oscillator signal and a divisor M to align subcarrier grids for said first and second baseband signals with DC.
