Abstract

We present the minimum mean squared error multiuser detector for noncoherent detection of non-orthogonal multipulse modulation. The detector is analyzed in the large signal-to-noise ratio regime and it is shown that the MMSE detector approaches a new multiple access interference suppressing detector, termed the multipulse decorrelating (MD) detector. The asymptotic performance of the detectors is presented for the additive white Gaussian noise noncoherent channel
