SNR gap between MIMO linear receivers: Characterization and applications
2016 IEEE International Symposium on Information Theory (ISIT)
This paper presents a statistical characterization of the SNR gap between MIMO Zero-Forcing (ZF) and Minimum Mean Squared Error (MMSE) equalizers, beyond the Rayleigh assumption for the interfering streams amplitude fading. Results are valid for arbitrary transmit SNR values and number of transmit/receive antennas. Specifically, we provide the exact closed-form distribution of the random variable representing the difference between the output SNR on a generic receive filter branch, under MMSEdoi:10.1109/isit.2016.7541315 dblp:conf/isit/AlfanoCN16 fatcat:gcbngfl6pjeitkskeotde3mkl4
