ABSTRACT:
A digital data communication system for transmitting data over a transmission channel. The system is capable of estimating a channel impulse response with high reliability even when the channel is time-varying and suffers from intersymbol interference. Even when the variation on the channel is rapid, the system reduces the influence of demodulation delay particular to a maximum likelihood sequence estimator and thereby realizes highly reliable data transmission.
