摘要： Disclosed is an adaptive control apparatus having an error calculation unit for calculating the difference between a reference signal and a feedback signal, and an adaptive controller for applying adaptive control so as to diminish the difference and causing the result of adaptive control to be reflected in the reference signal. The adaptive control apparatus has a delay unit for delaying at least one of the reference signal and feedback signal by a set delay time in such a manner that the reference signal and feedback signal will be input simultaneously to the arithmetic unit; a frequency-component detecting unit for detecting a frequency component of the reference signal; a delay-time acquisition unit for acquiring delay time conforming to the frequency component; and a delay-time setting unit for setting the acquired delay time in the delay unit.

摘要： A plurality of carriers are divided into two systems, one on a low-frequency side and the other on a high-frequency side, a transmitting unit that executes processing for transmitting a signal wirelessly is provided in each of the two systems, and output lines of transmit amplifiers of each of the transmitting units are directly coupled and input to an antenna. A feedback unit on the low-frequency side feeds a low-frequency carrier signal portion contained in the transmit signal back to a distortion compensating unit on the low-frequency side, and a feedback unit on the high-frequency side feeds a high-frequency carrier signal portion contained in the transmit signal back to a distortion compensating unit on the high-frequency side. The distortion compensating units compensate for distortion on the low- and high-frequency sides.

摘要： Apparatus (20) and methods (50) that compensate for the effects of gain and phase variations of a high power amplifier (40) in the presence of multicarrier traffic. The calibration system (20) and method (50) impose negligible degradation to the multicarrier traffic processed by the high power amplifier (40). A calibration signal generator (21) is used to generate (51) a plurality of nondisrupting calibration signals, such as pseudorandom numbers, which are also summed (23,52) and combined (31,53) with the multicarrier traffic signals. The plurality of nondisrupting calibration signals are also combined (24,54) to produce a combined nondisrupting calibration signal. Each of the nondisrupting calibration signals is selectively output (22,55) and is combined (26,57) with sampled (56) versions of the amplified multicarrier traffic signals produced by the high power amplifier (40) to despread them. The despread multicarrier traffic signals are then processed (58) in a processor (28) to generate signals indicative of total signal power, intermodulation power, and phase shift of the de-spread multicarrier traffic signals to determine a current operating point of the high power amplifier on its gain transfer curve. Gain and phase control signals are generated (59) by a processor (28) that are coupled to the gain control (32) and phase control (33) circuits to set the amplifier at its most desirable operating points.

摘要： A RF-digital hybrid mode power amplifier system for achieving high efficiency and high linearity in wideband communication systems is disclosed. The present invention is based on the method of adaptive digital predistortion to linearize a power amplifier in the RF domain. The present disclosure enables a power amplifier system to be field reconfigurable and support multi-modulation schemes (modulation agnostic), multi-carriers and multi-channels. As a result, the digital hybrid mode power amplifier system is particularly suitable for wireless transmission systems, such as base-stations, repeaters, and indoor signal coverage systems, where baseband I-Q signal information is not readily available.

摘要： Methods, systems and apparatus for modelling a power amplifier and pre- distorter fed by a multi-band signal are disclosed. According to one aspect, a method includes receiving a multi-band signal and generating a discrete base band equivalent, BBE, Volterra series based on the received multi-band signal, where the series has distortion products grouped according to determined shared kernels. The shared kernels are determined based on a transformation of a real-valued continuous-time pass band Volterra series without pruning of kernels.

摘要： A distortion reducing circuit compensates an upper side third-order distortion and a lower side third-order distortion produced by an amplifier for amplifying a fundamental signal including multiple frequency components. The distortion reducing circuit includes a second harmonic reflection coefficient regulation circuit, installed at an output side of the amplifier, for regulating reflection coefficients for multiple frequency components included in a second harmonic signal to have a constant value.
