Abstract :
Uniform M-PAM signal transmission over AWGN channel with two-level interference where the sequence of interference symbols is known causally at the transmitter is considered. Shannon´s theorem for channels with side information at the transmitter is used to formulate the capacity of the channel. It is shown that by using exactly M out of M2 inputs of the associated channel the capacity is achievable. Based on this, the general structure of a communication system with optimum precoding for the channel under consideration is proposed
