Performance Evaluation of Full Rate Space-Time Block Code for Multiple Input Single Output (MISO) Wireless Communication System
To enhance the capacity of a Multiple Input Single Output (MISO) system in wireless communications, the most widely used channel coding technique is the Space Time Block Coding (STBC). The outstanding orthogonal full rate STBC proposed by Alamouti is the most successful one and also very simple to implement, where only two transmit antennas and one receive antenna are used. As the number of antennas is increased beyond two, the orthogonality of the STBC is lost. Recent literature proposes a scheme known as the quasi-orthogonal STBC for full rate communication. It has been found that for ? and ? rate, the orthogonality of the code can be maintained.
