Multi-User (MU) Muliple Input-Multiple Output (MIMO) has become an essential technology to achieve IMT advanced requirements. Performance of limited feedback Multi-User MIMO in spatially and time correlated channels are investigated in this paper. A special attention is drawn to the case where users have the opportunity to adapt their codebooks as a function of their own channel statistics (i.e. transmit...
Codebook design for limited feedback Spatial Multiplexing commonly relies on the assumption of i.i.d. Rayleigh fading. It is well known that realistic MIMO channels may exhibit large correlation and/or dominant components and that antennas could be dual-polarized. Hence there is much appeal to come up with design criteria that can cope with such a large distribution of propagation conditions. In this...
