Abstract
The BER performance of concatenate block coded CDMA signal with coherent RAKE reception and complex spreading are considered in this paper. General multi-path intensity Nakagami fading and multiple-access near/far interference channel are assumed. A dedicated pilot channel for coherent demodulation is used for the purpose of channel estimation. Pilot channel estimation error, due to multiple-access interference and multi-path fading is studied. The analysis for system performance shows that the error of channel estimation significantly degrades BER performance and can be effectively suppressed by serial concatenate block code (SCBC) and parallel concatenate block code (PCBC) schemes. Also in this paper, an attempt for comparing the BER on different concatenate block coding schemes has been made. And a discussion on the multiple-access near/far interference is also included, which illustrates that it can be effectively limited by power control and SCBC/PCBC schemes.
