 401 views

This document describes an integrated acoustic signal processing system that provides adaptive noise cancellation, acoustic echo cancellation, and adaptive active noise control for hands-free cellular telephones. It discusses the software and hardware for the integrated acoustic signal processing systems, the testing of the system and its results. This application uses the TMS320C3x family of 32-bit floating-point digital signal processors (DSPs). This document is one of the 1995 TI DSP Solutions Challenge entries.
