High performance of MIMO-OFDM wireless systems is very much desirable. In this paper, we study the performance analysis of scheduling schemes for multiuser MIMO-OFDM systems employing Orthogonal Space-Frequency Block Coding in g-l fading scenario over frequency selective fading channels. We analyze the advantages of user scheduling in MIMO-OFDM systems employing OSFBC and adaptive modulation schemes. It can be noted that g-l distribution includes Nakagami-m and Hoyt distributions as special cases. Analytical expressions for average spectral efficiency (ASE), average bit error rate (BER), and outage probability for scheduling schemes are derived. Both full-feedback and limitedfeedback channel information scenarios are considered. Using the results obtained from both mathematical expressions and numerical simulations, the ASE and BER are compared and discussed.
