How accurate channel prediction needs to be for transmit-beamforming with adaptive modulation over Rayleigh MIMO channels?.

Adaptive modulation improves the system throughput considerably by matching transmitter parameters to time-varying wireless fading channels. Crucial to adaptive modulation is the quality of channel state information at the transmitter. In this paper, we first present a channel predictor based on pil...
