Abstract : | In the mobile cellular system, the DS/CDMA system takes advantage of diversity combining. Maximal ratio combining RAKE receiver, which is an ooptimal combining scheme, is an efficient way of combating channel fading. This paper is concerned with the channel estimation scheme needed in the maximal ratio combining RAKE receiver. To obtain coherent detection using the channle estimation, we use the reference symbol based estimation scheme. The performance of this system is compared with other estimation methods as well as noncoherent detection using BER as a measure of performance. |
