This paper reports the performance of Block Diagonalization (BD) scheme for different array antenna structures used in a multiuser Multiple Input Multiple Output (MIMO) system. The assessment is performed in terms of sum rate capacity. Theoretical analysis as well as computer simulations shows that the spatial correlation downgrades downlink performance of BD. The simulations also reveal that the...
This paper reports on channel estimation for a multiple input multiple output system, in which the transmitter is equipped with a linear array antenna while the receiver uses a circular array antenna. A model that includes spatial correlated channels and effects of mutual coupling is presented to investigate the performance of a training-based minimum mean-square error MIMO channel estimation method...
