Abstract
In a communication system, the combined advantages of decision feedback equalization and delayed decoding are achieved in a receiver by interleaving the signal points at the transmitter, and deinterleaving them at the receiver so that sufficiently reliable delayed decoder decisions can be used in estimating the distortion component of the received signal presently being processed in the decision feedback circuit.
