摘要
研究了i - id衰落下的三用户多输入多输出干扰信道，其中发射机具有延迟信道状态信息。考虑所有发射机和所有接收机分别配备M天线和N天线的情况。针对这种情况，提出了一种新的传输方案，该方案在3/4 <的范围内实现了比先前报道的更高的自由度;M / N <;1，其中方案参数确定为比值M/N的函数。与以前的方法相比，自由度的增加是由于更有效地使用了发射和接收天线。
On the degrees of freedom of the three-user MIMO interference channel with delayed CSIT
The three-user multiple-input multiple-output interference channel under i.i.d. fading is studied, where the transmitters have the delayed channel state information. The case where all transmitters and all receivers are equipped with M and N antennas, respectively, is considered. For this case, a new transmission scheme is proposed that achieves a number of degrees of freedom higher than previously reported for the range of 3/4 <; M/N <; 1, where the parameters of the scheme are determined as functions of the ratio M/N. The degrees of freedom gains compared to the previous approaches are due to the more effective use of transmit and receive antennas.
