Performance Investigation of Different Space-Time Codes for Future Wireless Communication
A Multiple-Input Multiple-Output (MIMO) wireless system uses multiple transmits and multiple receive antennas. The usage of multiple antennas provides a substantial increase in the capacity of the wireless system without requiring much increase in the system bandwidth. In this paper, the authors investigate the different space-time codes for future wireless transmission. The considered space-time codes in the paper are Alamouti STBC, Golden STBC and Silver STBC, the performance of considered STBC's is studied in frequency selective fading channel with and without OFDM which provides a real communication environment and it has been observed that Golden STBC provides the best result among other considered STBC's.
