摘要

这一贡献考虑了自适应(多输入多输出)mimo分集选择在接收机与闭环功率控制(PC)联合使用，以有效地对抗衰落只有少数发射(Tx)和接收(Rx)天线。因此，我们避免在没有PC的大型mimo阵列中进行天线选择，否则将需要保持低复杂性。低多普勒闭环PC显着提高了传输容量，减小了mimo阵列的尺寸。

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

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.
