Performance analysis of scheduling schemes for MIMO OSFBC-OFDM system in α-μ fading channel scenarios

High performance for MIMO-OFDM wireless systems is very much desirable. In this paper, we study performance analysis of scheduling schemes for multiuser MIMO-OFDM systems employing Orthogonal Space-Frequency Block Coding (OSFBC) in α-μ fading scenario over frequency selective fading channels. We analyze the advantages of using user scheduling in MIMO-OFDM systems employing OSFBC and adaptive modulation schemes. α-μ distribution includes Nakagami-m and Weibull distribution as special cases. Analytical expressions for Average Spectral Efficiency (ASE), average Bit Error Rate (BER), and outage probability for the scheduling scheme are derived. Both full feedback and limited-feedback channel information scenarios are considered. Using the results obtained from both mathematical expressions and numerical simulations, the ASE will be compared.
