Abstract
We propose a pre/post-RAKE combining technique using the RAKE structures at both the transmitter and the receiver. An optimal solution for the pre-RAKE and post-RAKE combining weights is presented using principal ratio combing (PRC). We have shown that the performance of the proposed pre/post-RAKE improves as the number of pre-RAKE fingers increases.
