Study of the Performance of 3x3 MIMO Transmission System Using MMSE and ML Detectors
Analysis of full-rate linear and space-time block code for 3X3 Multiple-Input Multiple-Output (MIMO) communication systems under a Rayleigh flat-fading environment has been carried out. The design targets specifically use a Linear Minimum Mean-Square Error (MMSE) and Maximum Likelihood (ML) receivers which minimizes the average Symbol Error Rate (SER) for a QPSK transmitted signal. The optimization problem is solved by minimizing a lower bound of the SER. The performance of MIMO systems has been studied by changing the number of transmitters and receivers.
