Abstract

This paper deals with the performance analysis of Spatial Multiplexing(SM) multiple input multiple output (MIMO) system with time reversal (TR) technology. Focus is given on the spatial multiplexing gain of MIMO than the diversity gain aspect with the notion that the idea of diversity is inseparably associated with the uncertainty of the channel. If transmitter knows Channel State Information (CSI) before transmission, potential benefits can be harvested. TR is used here, to provide Channel State Information (CSI) at the transmitter before transmission. With the features of temporal and spatial focusing, TR not only can provide immunity against fading for spatially multiplexed data stream but also help boost its Multi Stream Interference (MSI) limited performance by mitigating it. The performance analysis of SM-MIMOTR is carried out with the aim of average minimum error probability for quantity of interest data rate. The interest date rate is 19.07 Mbps, where as the average minimum error probably is set to be that of Single Input Multi Output (SIMO) maximum ratio combining system (MRC). BER of Single Input Single Output (SISO) system is also simulated for making comparison tangible. Simulation study shows that Bit Error Rate (BER) performance of the system with the data rate of interest nearly coincides with that of SIMO system at the range of 10-15db and is better than SISO in all simulated Eb/No points. Additionally, from the standpoint of tread off curve, between diversity gain and spatial multiplexing gain, the non linearity nature still holds.
