Title: Echo canceller training system
Inventor: HIRAGUCHI MASAYOSHI
IPC: H04B3/23
Filed: 1985-03-01
Abstract: PURPOSE:To attain high speed training by applying separately the training of a nearby echo canceller and a remote echo canceller. CONSTITUTION:A transmission signal S(t) of a MODEM is converted into a transmission data Sn subject to digital sampling by an A/D converter 1. A control circuit 9 sets a nearby echo canceller correction factor alpha to a prescribed value alpha0 when the echo canceller training sequence is started to zero the correction factor beta of the remote echo canceller. That is, only the training for the nearby echo canceller is applied. In this case, the alpha0 is selected to, e.g., 1/ (tap number), i.e., 1/N where the mean level of an Sn is selected as 1. When a two- way propagation delay time is elapsed and the remote echo is received, the correction factor alpha for the nearby end echo canceller is brought into 0 and only the training of the remote echo canceller set to the correction factor beta0 of the remote end echo canceller is applied. In this case, the beta0 is selected to, e.g., 1/M.
