DIGITAL VOICE ECHO CANCELLER WITH A TMS32020 (CONTAINS SCANNED TEXT)This report covers both the theory and implementation of a single chip TMS32020 digital voice echo canceller. The single-chip system can perform a 128-tap for 16-ms echo cancellation for telephone network applications. The echo canceller is implemented in accordance with the CCITT recommendation (G.165). A simulation has been performed to test the echo canceller, and the result exceeds the CCITT requirements.
