Adaptive receiver for multiplex/multi-access communications

摘要

A received communication signal in which input data has been differentially encoded using a number of nominal symbols is filtered according to variable filter coefficients. A symbol is predicted based on the filtered signal, as if the input data had been encoded non-differentially in the communication signal. The filter coefficients are updated in response to the predicted symbol. An example of the differential encoding is differential phase shift keying (DPSK) modulation.
