Abstract :
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 diversity and block diagonalization precoding method to improve system capacity with good error performance for 802.11n WLAN system. The results of Matlab simulation show the improvement of system capacity in 802.11n wireless indoor environment.
