摘要

Multiple-input multiple-output (MIMO) systems are an important element in the recent wireless communication. Space Time Codes (STCs) and Space Multiplexing (SM) are mandatory for the WIMAX systems. The Almouti's code has played an important role for the growth and development of these systems. But, the Alamouti's code is with low data rate (half rate). For this, some research activities aimed to increase the data rate have been made. In particular, this paper deals with combining Alamouti's code and the orthogonal codes in order to benefit from the full diversity, to increase the data rate and to keep the system simple as much as possible.
