Because of the rapid growth of digital communication in recent years, the need for high speed data transmission is increased. Orthogonal Frequency Division Multiplexing (OFDM) technique is suitable for high speed communication because of its resistance to ISI (Inter-Symbol Interference) and it utilizes the bandwidth efficiently. OSTBCs are an attractive technique for MIMO wireless communications. They exploit full spatial diversity order and enjoy symbol-wise Maximum Likelihood (ML) decoding. However, they offer no coding gain. The combiner for OSTBC at the receiver side provides soft information of the transmitted symbols, which can be utilized for decoding or demodulation of an outer code.
