Multichannel Teleconferencing System with Multi Spatial Region Acoustic Echo Cancellation
نویسندگان
چکیده
In this paper a novel configuration for multichannel teleconferencing with multi spatial region acoustic echo cancellation is developed. In the proposed configuration, the transmission and receiving rooms are divided into equivalent number of spatial regions and adaptive filters are attached to each spatial region for the purpose of echo cancellation. This multi spatial region acoustic echo canceller (AEC) does not suffer from nonuniqueness problem and it involves less computational complexity compared to conventional multichannel AEC. Furthermore, the proposed multi spatial region teleconferencing configuration requires narrower transmission bandwidth. Simulation results show the effectiveness of the proposed configuration.

A Multi-filter Approach to Acoustic Echo Cancellation for Teleconferencing
We have designed and tested an acoustic echo cancellation system for speech teleconferencing. Our algorithm is based on a least-mean-square (LMS) frequency domain adaptive filter (FDAF) and uses a novel filter-update technique using many (at least 3) simultaneously running filters. We find the new multi-filter to converge faster than similar LMS FDAF’s for echo cancellation, and find it to be e...
متن کاملAdvanced Applications for Multichannel Teleconferencing Audio Systems
This thesis deals with advanced digital signal processing techniques applied to multichannel teleconferencing audio systems, focusing on their benefits and drawbacks. A teleconferencing system should provide a realistic representation of visual and sound fields, allowing a natural communication among participants anywhere in the world as they were all in the same room. In this context, the work...
متن کاملStereophonic acoustic echo cancellation system using time-varying all-pass filtering for signal decorrelation
This paper describes a novel technique for decorrelating the stereo signals in stereophonic acoustic echo cancellation (AEC) systems. At present, most teleconferencing systems use a single full-duplex audio channel for voice communications. However, in order to introduce spatial realism, future teleconferencing systems are expected to have more than one channel (at least stereo with two channel...

Adaptive Acoustic Echo Cancellation in stereophonic teleconferencing is a very demanding application. Characteristics are : very large number of coe cients, non-stationary input (speech), (slowly) time-varying systems to be identied, plus the speci c property that both stereo signals are intrinsically very correlated. Basic versions of stochastic gradient algorithms have di culties to meet thes...
متن کاملChapter 1 ADAPTIVE ALGORITHMS FOR MIMO ACOUSTIC ECHO CANCELLATION
The first thing that comes in mind when we talk about acoustic echo cancellation is adaptive filtering. In this chapter, we discuss a large number of multichannel adaptive algorithms, both in time and frequency domains. This discussion will be developed in the context of multichannel acoustic echo cancellation where we have to identify a multipleinput multiple-output (MIMO) system (e.g., room a...
