Abstract :
In this paper, a rake diversity combining scheme for detection of a single data stream in ultra-wideband (UWB) multiple input multiple output (MIMO) systems is considered as an extension of single input multiple output (SIMO) systems. The BER performance of a linear receive rake diversity scheme is presented in a log-normal multipath fading channel. It is shown that the increase of an antenna dimension happens to degrade the performance in the range of high SNRs. It is seen that as the number of transmit and receive antennas increases, the rake diversity combining system improves the performance at low SNRs or in the case of large antenna dimension at high SNRs.
