Apparatus and method for distortion compensation of high power amplifier in DS-multicode CDMA system

摘要

A device and method for compensating for distortion with use of a high power amplifier in a multi-code mobile communication system. In the distortion compensating device, a plurality of receivers regenerate corresponding user multi-channel signals from an input signal, an interference canceler subtracts the signals regenerated in the other receivers from the input signal, to thereby cancel the interference of the other user signals, and a distortion compensator calculates Euclidean distances between regenerated candidate information and the output of the interference canceler, using multi-channel symbols decided in the corresponding receiver and determines the candidate information with the smallest Euclidean distance.
