摘要： In an amplifying apparatus performing distortion compensation by imparting pre-distortion, a table for distortion compensation is efficiently updated for improving the accuracy of distortion compensation even when the frequency of occurrences of levels near a peak of an input signal is low. Compensation values in a distortion compensation table 2 are divided into a first group of compensation values associated with great input levels resulting in great distortion of output and a second group of compensation values associated with other small input levels. A control unit 5 updates the first group of compensation values when a level detected by a level detecting unit 1 is equal to or greater than a threshold and updates the second group of compensation values when the level is equal to or smaller than the threshold. The updating process can be efficiently performed even for signals having a low frequency of occurrences of signal level peak values such as CDMA- and OFDM-type signals, and the accuracy of distortion compensation is improved.

摘要： It is intended to increase the efficiency of a distortion compensation amplification device having a pre-distorter 1. Level detecting means 11 detects a signal level, correspondence storage means 12 outputs a distortion compensation coefficient depending on the signal level, pre-distortion executing means 13 gives distortion with an inverse characteristic to the signal, filtering means 8 outputs a distortion component from a feedback signal output from an amplifier 4, and correspondence acquiring means 14 updates a learning coefficient constituting a function that gives the inverse characteristic so as to reduce the distortion component. The function that gives the inverse characteristic is expressed using a set of orthogonal polynomials. Each orthogonal function is the total sum of products of functions of the input signal and parameters, and the parameter values are set to cause the orthogonal functions to be orthogonal to each other when functions, which are obtained by applying a filter having the same characteristic as that of the filtering means 8 to the functions of the input signal, are replaced for the functions of the input signal constituting the orthogonal functions.

摘要： A predistortion distortion signal generating unit uses a signal to be amplified to generate a predistortion distortion signal including odd-order signal components of the signal. A delay time difference adjusting unit adjusts a delay time difference between a signal to be amplified and a distortion signal for predistortion such that an influence by the memory effect occurring in the amplifier can be reduced. A predistortion distortion signal giving unit gives a predistortion distortion signal to a signal to be amplified in a form that the delay time difference is adjusted.
