在假设所有接收机都将干扰视为加性高斯噪声的情况下，我们研究了多输入单输出(MISO)干扰信道的可达速率区域。我们的主要结果是对任意数量的用户和天线的帕累托边界进行了显式的参数化。该参数化用低维流形描述边界。对于两个用户的情况，我们证明了每个用户的单个实值参数足以实现Pareto边界上的所有点，并且Pareto边界上的任何点对应于波束形成向量，这些波束形成向量是迫零(ZF)和最大比传输(MRT)波束形成器的线性组合。我们进一步将结果专门提供给MISO广播频道(BC)。数值算例说明了结果。
In this correspondence, we study the achievable rate region of the multiple-input single-output (MISO) interference channel, under the assumption that all receivers treat the interference as additive Gaussian noise. Our main result is an explicit parametrization of the Pareto boundary for an arbitrary number of users and antennas. The parametrization describes the boundary, in terms of a low-dimensional manifold. For the two-user case we show that a single real-valued parameter per user is sufficient to achieve all points on the Pareto boundary and that any point on the Pareto boundary corresponds to beamforming vectors that are linear combinations of the zero-forcing (ZF) and maximum-ratio transmission (MRT) beamformers. We further specialize the results to the MISO broadcast channel (BC). A numerical example illustrates the result.
