本文给出了在中等和高信噪比下单用户多天线信道容量的解析表达式，该容量由发射机和接收机同时知道。包含不相关和相关天线的衰落信道。表征主要是在大量天线的限制下进行的，附带的示例说明即使天线数量很少，结果的有效性。在没有相关性的情况下，对于固定数量的天线，容量也是紧有界的，具有紧致的封闭形式表达式。
This paper presents analytical expressions for the capacity of single-user multi-antenna channels, known instantaneously by both transmitter and receiver, at moderate and high signal-to-noise ratios. Fading channels with both uncorrelated and correlated antennas are encompassed. The characterization is conducted primarily in the limit of large numbers of antennas, with accompanying examples that illustrate the validity of the results for even small numbers thereof. In the absence of correlation, the capacity is also tightly bounded for fixed numbers of antennas with compact closed-form expressions.
