For the applications of the BER of the optimum base-band system on band-limited channel, this article analysis the error performance for the optimum digital receiver of the band-limited base-band channel, therefore the relation between the bit energy and the parameters of the system is determined. Then the optimum digital base-band system of the band-limited channel is constructed and the error performance is simulated on the SystemView. The simulation shows that the analysis result is correct.
