Abstract
Presents a performance analysis of a decorrelating detector for differentially coherent transmission over a CDMA frequency-nonselective Rayleigh fading channel. While the correlation-type receiver is near-far limited in this channel, it is shown that the aforementioned multiuser detector eliminates the bit error rate floor and alleviates the near-far problem.<>
