Some asymptotic capacity results for MIMO wireless with and without channel knowledge at the transmitter

We study the asymptotic capacity of MIMO wireless channels predicated on channel knowledge (or channel state information - CSI) at the transmitter in the high SNR regime. The transmitter CSI studied includes instantaneous and transmit correlation types. The receiver is assumed to know the channel perfectly. Analytical expressions for the asymptotic ergodic capacity are derived in each case, which closely match the simulations. The results show that transmitter CSI in MIMO wireless can have a strong influence on capacity.
