Precoding is an efficient approach to obtain high channel capacities and high quality in multiple-input-multiple-output systems and draws much attention in recent researches. In the codebook-based precoding systems, the tradeoff between performance and feedback overhead should be considered. In this paper, a novel version of the Linde-Buzo-Gray (LBG) algorithm is first utilized in the codebook design...
In this contribution, Space-Time Block Coding (STBC) Code Division Multiple Access (CDMA) system is simulated to investigate the effect of spatial correlation of Multiple-input multiple-output (MIMO) wireless channels. In practical situations the MIMO antennas are spatially correlated, due to the lack of spacing between them or weak scattering. The correlative model is considered for MIMO channel...
