Abstract
The receiving end of a data communication system requires a digital filter - an equalizer - to correct distortions induced by the channel. The optimum tap coefficients of an equalizer need to be determined in realtime for a time-varying channel. A microprocessor-based implementation of an equalizer is proposed, and the hardware/software design given. Results show that a microprocessor-based implementation of an equalizer for data communication systems using voice channels is feasible in realtime. The system was implemented on a PC XT based on 8088/8087 processors, but is easily adaptable to faster microprocessors that are available today.
