ANALYSIS OF SPACE-TIME BLOCKCODED SYSTEM FOR WIRELESSCOMMUNICATION

[摘要] In this paper analytic and experimental result on space-time block codes (STBCs) of various diversity orders including an assessment of its result by means of computer simulation are illustrated. STBCs originally introduced by Alamouti, have evolved as a revolution coding scheme in modern wireless communication field. Here, after presenting a general overview of MIMO systems, we will compare the performance results of STB codes of various diversity orders through computer simulations. Then we will determine the optimum diversity order of STB codes for the MIMO systems.
