Title: Echo canceller
Inventor: FURUKAWA HIROMOTO
IPC: H04B3/23
Filed: 1986-07-08
Abstract: PURPOSE:To eliminate the need for a training signal at the start of an echo canceller and to suppress echo or howling due to the fluctuation of an echo path by giving the loss of a voice switch of a degree not causing howling at the start of application of the echo canceller and controlling the canceller adaptively. CONSTITUTION:The voice switch 7 has a loss not causing howling at the start of the application of the echo canceller 5. An echo path loss arithmetic means 9 obtains the loss of the echo path including the echo canceller 5, an insertion loss arithmetic means 10 operates the insertion loss to be inserted, a low reduction means 13 decreases the stored loss in a range not exceeding the converging speed of the echo canceller, a maximum value selection means 12 compares the operated echo path loss with the decreased loss, stores lose which is larger in a loss storage means 11 as a loss and a margin addition means 14 provides howling margin. As the application of the echo canceller is advanced, the process above is repeated to decrease the insertion loss. When the detector 8 detects howling at the start of the fluctuation of the echo path, the storage means 11 replaces the loss into that at the start of application.
