Abstract

d.t.n. professor SibGUTI 2 engineer -researcher VimpelCom 3 engineer -researcher OAO MegaFon 4 k.t.n., associate professor SibGUTI Abstract -conducted the operation algorithm of invariant first-order echo canceller. The main specifications -power intrinsic noise and noise power undercompensation.The comparison of the specifications developed by the echo canceller with the characteristics of the classical echo canceller Widrow.Index Terms -invariant, echo canceller, stability.
