Abstract: It is well known that interpath interference (IPI) is a major factor that limits the performance of high data rate transmissions over a variable spreading factor wideband-CDMA (W-CDMA) link since the spreading factor is in general small. An optimum combining scheme suppressing IPI was recently proposed for RAKE reception in [1]. The main contribution of this letter is to present a theoretical model for the outage probability and bit error probability of a RAKE receiver utilizing the optimum combining scheme. Analytical and simulation results are closely matched and show that the optimum scheme provides significant performance improvement compared to the conventional maximum ratio combining (MRC) scheme.
