BER Analysis of 2x2 MIMO Spatial Multiplexing Under A and Rician Channels for Different Modulations Techniques
Multiple-Input-Multiple-Output (MIMO) wireless systems use multiple antennas at transmitting and receiving end to offer improved capacity and data rate over single antenna systems in multipath channels. In this paper, the authors have investigated the Spatial Multiplexing technique of MIMO systems. Here different fading channels like AWGN and Rician are used for analysis purpose. Moreover they analyzed the technique using high level modulations (i.e. M-PSK for different values of M). Detection algorithms used are zero-forcing and minimum mean square estimator.
