Baseband Development System Implementation
Abstract
The real-time implementation of a voiceband communication channel simulator on the TMS32020 digital signal processor is presented. Several channel characteristics are simulated including attenuation distortion, group delay distortion, harmonic distortion, listener echoes, frequency offset, gaussian noise, and impulsive noise. One of the problems encountered in evaluating the performance of various communications equipment such as group delay meters, channel equalizers, and voiceband modems is the need to test them under realistic operating conditions, similar to those encountered during their actual use. These tests could be carried out on actual channels, but the cost and the need to access both ports of a channel make it prohibitive and impractical for all but a few equipment designers. Even then, using real lines gives the designer a limited choice of channel responses. Channel simulation then becomes not only a viable alternative, but a desirable one as well. (kr)
