Description for Perspective on Stereophonic Acoustic Echo Cancellation
Hardcover. This volume assesses the difficulties involved in real-time communication via a single-input/single-output system with complex random variables. As a result, the most important aspects of a SAEC are presented, including the identification of the echo paths with adaptive filters, double-talk detection, and suppression. Series: Springer Topics in Signal Processing. Num Pages: 145 pages, biography. BIC Classification: PHDS; TTA. Category: (P) Professional & Vocational. Dimension: 242 x 163 x 11. Weight in Grams: 358.
Single-channel hands-free teleconferencing systems are becoming popular. In order to enhance the communication quality of these systems, more and more stereophonic sound devices with two loudspeakers and two microphones are deployed. Because of the coupling between loudspeakers and microphones, there may be strong echoes, which make real-time communication very difficult. The best way we know to cancel these echoes is via a stereo acoustic echo canceller (SAEC), which can be modelled as a two-input/two-output system with real random variables. In this work, the authors recast this problem into a single-input/single-output system with complex random variables thanks to the widely linear ... Read more
