Study of Extended SM scheme over Generalized α — µ fading channel

In this paper, performance of Extended Spatial Modulation (ESM) scheme for multi input multi output systems over uncorrelated flat fading α - μ channel have been evaluated using simulation and studied. The existing sub-optimal threshold detection method with lesser complexity is implemented at the receiver. The effects of varying the transmitter diversity, spectral efficiency and receiver diversity on the bit error rate (BER) performance have also been discussed. The comparative study of spectral efficiency ESM with spatial modulation SM has also been presented.
