BER analysis of SM-MIMO systems with MRC detectors over Weibull fading channels

In this study, bit error rate (BER) performances of 2×4 and 2×8 spatial modulation multiple input multiple output (SM-MIMO) systems over Weibull fading channels are investigated. Transmitted data and the transmitter antenna which conveys the data are estimated by using iterative maximum ratio combining algorithm at the receiver side. BER performance is obtained by changing the value of fading parameter and the level of modulation for several scenarios with computer simulations. While reducing the computational complexity of similar SM-MIMO system which uses maximum likelihood for the estimation procedure, it is obtained up to 13 dB better performance.
