我们研究了在加性高斯信道的点对点通信系统两端使用多天线。我们考虑一个有t个发射天线和r个接收天线的系统，其中接收向量v/spl isin/C/sup /spl tau//依赖于发射向量u/spl isin/C/sup /spl tau//通过：v=Hu+w，其中H/spl isin/C/sup r/spl乘以/t/是信道传输矩阵，w是零均值复圆对称高斯噪声。我们假设E[w]=/spl σ //sup 2/I/sub r/。发射机受其总功率的限制，即E[uu]/spl les/E/sub s/。我们假设在通信系统的两端信道矩阵H是已知的，并且波形信道在感兴趣的带宽上是平坦的。
We investigate the use of multi-antennas at both ends of a point-to-point communication system over the additive Gaussian channel. We consider a system with t transmit antennas and r receive antennas in which the received vector v/spl isin/C/sup /spl tau// depends on the transmitted vector u/spl isin/C/sup /spl tau// via: v=Hu+w where H/spl isin/C/sup r/spl times/t/ is the channel transfer matrix and w is zero-mean complex circular symmetric Gaussian noise. We assume that E[ww]=/spl sigma//sup 2/I/sub r/. The transmitter is constrained in its total power, i.e., E[uu]/spl les/E/sub s/. We assume that the channel matrix H is known at both ends of the communication system, and that the waveform channel is flat over the bandwidth of interest.
