摘要

对受无记忆相位噪声影响的MIMO无线信道的互信息进行了表征。对视距MIMO链路和多天线基站下行信道进行了研究。对于这两种情况，导出了低信噪比下互信息的封闭近似。其次，利用获得的近似，利用多数化理论和交替最大化设计可实现速率最大化的功率控制策略。

Mutual information of phase-noise impaired wireless networks

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.
