Abstract :
The mutual information of a MIMO wireless channel, impaired by memoryless phase-noise, is characterized. Both a Line-of-Sight (LOS) MIMO link and a downlink channel with multiple-antenna base station (BS) are studied. For both cases, closed-form approximations of the mutual information in the low-SNR regime are derived. Next, leveraging the obtained approximations, power control policies for achievable rate maximization are designed by means of majorization theory and alternating maximization.
