我们提出了一些新的结果可靠的信息速率支持点对点多天线瑞利衰落的无线链路编码传输，采用二维（QAM或PSK）的数据星座。推导出这些链路的对称容量后，我们提出了快速计算的分析上限和下限，是渐近准确的高和低信噪比，并产生一个可靠的评估时，完美的信道状态信息（CSI）是在接收机的链路容量。此外，渐近精确的简单的上界也提出了一个严格的中断概率的评估。
We present some novel results about the reliable information-rate supported by point-to-point multiple-antenna Rayleigh-faded wireless links for coded transmissions that employ two-dimensional (QAM or PSK) data constellations. After deriving the symmetric capacity of these links, we present fast-computable analytical upper and lower bounds that are asymptotically exact both for high and low SNRs, and give rise to a reliable evaluation of the link capacity when perfect channel state information (CSI) is available at the receiver. Furthermore, asymptotically exact simple upper bounds are also presented for a tight evaluation of the outage probability.
