Title: Echo canceller and voice communication apparatus
Inventor: SAKAI MAKOTO
IPC: H04B3/23
Filed: 2002-07-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide an echo canceller capable of properly eliminating an echo signal.  <P>SOLUTION: An acoustic echo canceller section 30 acquires a voice signal Xin2(t) from an external communication apparatus and a voice signal Xout1(t) outputted from a microphone (S250). Further, the acoustic echo canceller section 30 applies convolution arithmetic operation to the voice signal Xin2(t) and a filter coefficient W1[j] to produce a cancel signal F1(t) for eliminating an echo signal in a correction learning processing (S310). Then the acoustic echo canceller section 30 adds the cancel signal F1(t) to the voice signal Xout1(t) to obtain a voice signal Xout2(t) from which the echo signal is eliminated (S320). Moreover, the acoustic echo canceller section 30 uses the Xout2(t), the Xin2(t), and the filter coefficient W1[j] to calculate a new filter coefficient according to the expression on the basis of the infomax method for updating the filter coefficient.  <P>COPYRIGHT: (C)2004,JPO
