Abstract :
We present an optimum multiuser receiver for detecting K cochannel asynchronous partial-response pulse amplitude modulated (PAM) signals. The receiver generalizes the optimum multiuser detector developed by Verdu (1983, 1986) for asynchronous full-response PAM signals and the optimum single-user receiver developed by Ungerboeck (1974) for the detection of ISI-corrupted PAM signals.
