Item Performance of Iterative Multiuser Decoding and Channel Estimation in WCDMA Systems(2000-05-20) Bhashyam, Srikrishna; Hottinen, Ari; Center for Multimedia Communications (http://cmc.rice.edu/)This paper studies the performance of iterative multiuser decoding, interference cancellation, and channel estimation techniques applicable to third generation WCDMA systems. The concept uses a posteriori probabilities of code symbols to enhance detection, decoding and channel estimation in an iterative fashion. Performance is analyzed in a multi-path channel with simulations. It is seen that the proposed concept combats multiuser interference effectively and performs almost as well as single user systems.
