在接收端将干扰视为加性高斯噪声，发送端仅具有统计信道知识的假设下，研究了双用户多输入单输出干扰信道的可达遍历率区域。首先，我们给出了遍历率的封闭表达式，并推导出纳什平衡和零强迫发射波束形成策略。然后，我们证明了上述自私和利他策略的组合分别实现了帕累托最优速率对。
We study the achievable ergodic rate region of the two-user multiple-input single-output interference channel, under the assumptions that the receivers treat interference as additive Gaussian noise and the transmitters only have statistical channel knowledge. Initially, we provide a closed-form expression for the ergodic rates and derive the Nash-equilibrium and zero-forcing transmit beamforming strategies. Then, we show that combinations of the aforementioned selfish and altruistic, respectively, strategies achieve Pareto-optimal rate pairs.
