A New Full-diversity Space-time Block Code

Liu Chen

Open publisher page 0 citations

Abstract

In this paper,the inferential reasoning process of the space-time code design criteria is introduced in the frequency non-selective slow fading channels.Some performance analysis and comparison of several existing space-time codes are also done.Through reconstructing the DBOAST space-time block code,a new performance optimal space-time code called ABCD is proposed,in this case that there are 4 transmit antennas,which can achieve a rate of 2 symbols pcu and get full diversity.The new code combines the structure characteristics of Alamouti and Threaded Algebraic Space-Time(TAST) Block Codes.The simulation results show that the ABCD code provides larger second-order mutual information and thus is of a superior performance.
