The impact of atmospheric impairments on the bandwidth efficiency of multiple-input multiple-output (MIMO) geostationary satellite links is investigated theoretically. In particular we analyze the impairments caused by precipitation because especially rain and wet snow are the most severe atmospheric impact factors degrading the channel capacity. We focus on Line-of-Sight (LOS) MIMO links that are...
A low complexity space-time chip semiblind multiuser receiver based upon an adaptive mixing parameter and adaptive step-size for MIMO STBC downlink MC-CDMA with CPICH systems and without CP is proposed. The receiver exploits information from training and desired user signals for updated the algorithm. Information from training and blind modes are combined using an adaptive mixing parameter LMS algorithm...
