In current 4G systems growing demand of multimedia services and the growth of internet related contents lead to increasing interest to high speed communications. One indispensable problem of the wireless channel is fading, which can be mitigated by diversity. There are various coding methods to achieve high reliability for Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems earlier. Recently, Space Time Block Codes (STBCs) have gained much attention as an effective transmit diversity technique to provide reliable transmission with high peak data rates to increase the speed and performance of wireless communication systems.
