As the demand of high quality service in next generation wireless communication systems, a high performance of data transmission requires an increase of spectrum efficiency and an improvement of error performance in wireless communication systems. In this paper, we propose a multi-user multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system with cyclic delay...

A recent trend of research on the MIMO-OFDM system pays more attention to reduce complexity for implementation in design receiver structure. So in this paper, we propose differential space time block codes (STBC) MIMO-OFDM system with cyclic delay diversity (CDD) in a frequency selective fading channel. Differential modulation provides simplification of embodiment communication system because channel...
In a conventional MIMO-OFDM system, it is well known that cyclic delay diversity (CDD) and space-time block coding (STBC) can increase data rate, capacity and bit error rate (BER) performance. However, a recent trend of research on the MIMO-OFDM system pays more attention to simplified implementation of receiver structure. In this paper, we propose differential STBC MIMO-OFDM system with CDD. This...
