A new technique for high quality acoustic echo cancellation in teleconference and speaker phone systems has been developed. The new echo canceler is based on an enhanced adaptive filtering algorithm and uses a spread-spectrum-based technique to mitigate the effects of double talk. The test facility used to develop this new acoustic echo canceler and the system design of echo canceler are described.
