Generalised closed-form symbol error rate analysis for Orthogonal Space-Time Block Coded OFDM system

In this paper, the Symbol Error Rate (SER) performance for Orthogonal Space- Time Block Coded (OSTBC) Orthogonal Frequency Division Multiplexing (OFDM) systems over Nakagami-m fading channels is analysed. A novel closed-form SER expression is proposed, which incorporates the Gauss hypergeometric function and Appell hypergeometric function into the conventional Probability Density Function (PDF) approach. The proposed exact closed-form SER expression is a generalised solution since it perfectly captures OSTBCOFDM systems' performances when having different antenna configurations that employ various modulation schemes and which experience various fading conditions. Finally, Monte Carlo simulation results are provided to demonstrate the exact match between the simulation results and the proposed analytical expressions.
