摘要: In the high-SNR regime, multi-antenna mutual information behaves as an affine function of SNR|/sub dB/, described by multiplexing gain, which quantifies multiplicative increase number antennas, and power offset (zero-order term in dB). The conventional analysis that considers only gain is unable to assess impact channel features such Rician factor since, irrespective thereof, equals minimum transmit receive antennas. at high SNR can be conveniently quantified through corresponding offset, this paper evaluates closed-form.
