Abstract | In this paper, we study the performance of a general linear coherent multiuser receiver with pilot-symbol-assisted channel estimation (PSA-CE) for doubly-selective Rician-fading CDMA channels. Employing the multivariate Gaussian approximation (MGA) and a decision variable-based moment generating function (MGF) approach, both exact and low-complexity approximate bit error probability (BEP) formulas are presented. Some new findings are illustrated by numerical results. |
