Matlab simulation for diversity in 8×2 MIMO system using OSTBC

This paper simulates the Diversity performance of 8×2 MIMO system. Diversity was achieved through the use of orthogonal space-time block coding technique (OSTBC) at the transmitter, which is a recent innovation motivated by the need for higher throughput in wireless channel [4]. Matlab is used to simulate 8×2 MIMO system, and OSTBC to encode the BPSK modulated signal before being transmitted through flat fading Rayleigh channel. At the receiving end, the received signals were combined by Maximal Ratio Combiner (MRC) and detected by Maximum-Likelihood (ML) detector. The 8×2 simulations achieved low BER without the need for high SNR values.
