Abstract

Consider a digital transmission over a time-and frequency-selective, i. e., doubly-dispersive channel with additive white Gaussian noise being present in the system. It is well known that the optimum receive filter prior to symbol sampling is an adaptive filter that is matched to the transmit pulse and the in general time-varying channel. It achieves maximum signal to noise ratio (SNR) at the sampling instant. However, tracking a rapidly time-varying channel is demanding and estimation errors may degrade the theoretically optimal performance of such an adaptive receive filter.
