Adaptive MIMO-diversity selection with closed-loop power control over wireless CDMA rayleigh-fading channels

Abstract

This contribution considers adaptive (multiple input multiple output) MIMO-diversity selection at the receiver jointly with closed-loop power control (PC) to efficiently combat fading with only few transmit (Tx) and receive (Rx) antennas. Hence we avoid resorting to antenna selection among large MIMO-arrays without PC which would be otherwise required to keep complexity low. With low Doppler closed-loop PC significantly increases the transmission capacity and reduces the MIMO-array size.
