Performance of parallel interference cancellation for CDMA with delay estimation
Markku J. Juntti, Matti Latva‐aho, Kimmo Kansanen · 2003
While multiuser receivers for code-division multiple-access (CDMA) systems have been extensively developed in the past, there performance in fading channels with practical delay and channel estimation has gained very little attention. The performance of the hard-decision parallel interference cancellation (HD-PIC) multiuser receiver in frequency selective fading channels is studied. A practical complex channel gain and delay estimation are applied. The results show that the performance of the PIC receiver remains superior even in the presence of a practical delay estimator.
