This book brings together many advanced topics in network and acoustic echo cancellation which are aimed towards enhancing the echo cancellation performance of next-generation telecommunication systems. The general subject nature relates to algorithms with increased convergence speed, improved detection of double-talk from near-end speech, robust immunity to undetected double-talk, increased computational efficiency, and multi-channel capability. The resulting compendium provides a coherent treatment of such topics not found otherwise in journals or other books. The chapters are related with a common terminology, but still can be read independently.
