É bem conhecido que a interferência entre caminhos (IPI) é um fator importante que limita o desempenho de transmissões de alta taxa de dados através de um link CDMA de banda larga com fator de espalhamento variável (W-CDMA), uma vez que o fator de espalhamento é em geral pequeno. Um esquema de combinação ideal que suprime IPI foi recentemente proposto para recepção RAKE em [1]. A principal contribuição desta carta é apresentar um modelo teórico para a probabilidade de interrupção e probabilidade de erro de bit de um receptor RAKE utilizando o esquema de combinação ótima. Os resultados analíticos e de simulação são estreitamente combinados e mostram que o esquema ideal proporciona uma melhoria significativa de desempenho em comparação com o esquema convencional de combinação de razão máxima (MRC).

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.
