Abstract


This paper investigates 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.

 

 


Keywords


Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM), Space Time Block Code (STBC), Channel State Information (CSI), Quasi-Orthogonal STBC (QO-STBC).
