摘要

PROBLEM TO BE SOLVED: To provide a receiver the reproduction probability of which is improved for received signals containing colored noise. ;SOLUTION: Communication containing information, colored noise, and white noise is received (step 102), and the colored noise is reduced by generating a pre-whitening filter (step 104). Then the received information is reversely diffused by performing the demodulation of the filtered received signals and channel weighting (step 106). Consequently, colored noise-compensated information is obtained by selectively emphasizing the received signals.;COPYRIGHT: (C)2000,JPO
