Resumo: | It is intended to specify a new pre-distortion (PD) filtering technique to be used with a RAKE Receiver, which can be used to combat the Multiple Access Interference (MAI), combined with two kinds of Transmit Diversity (TD), namely the Selective Transmit Diversity (STD) and the Space-Time Transmit Diversity (STTD) for high data rate transmissions over frequency selective Rayleigh fading channels. By pre-distorting the signals to be transmitted by the Base Station (BS) with a Minimum Variance (MV) algorithm, the orthogonality between the desired signal and all interfering signals can be improved. We combine the PD with STD and with STTD, allowing a reduction in the MAI and combating the fading. The increase in performance is achieved with a small increase in power processing in the BS, avoiding any need to increase complexity in the Mobile Station (MS). |
