标题： Self-Interference in Full-Duplex Multi-User MIMO Channels

摘要： 我们考虑一个多用户多输入多输出（MIMO）设置，其中全双工（FD）多天线节点应用线性波束成形器，在Rician衰落信道上同时传输和接收多个数据流。 涉及非独立同分布随机变量之和的平方范数的残留自干扰（SI）的精确一阶和二阶正矩，以闭合形式推导得出。 因此，采用矩方法为残留SI分布提供一个Gamma近似。 所提出的定理在任意线性预编码器/解码器设计、天线数量和数据流数量以及SI消除能力下均成立。 显示英文摘要

摘要： We consider a multi-user multiple-input multiple-output (MIMO) setup where full-duplex (FD) multi-antenna nodes apply linear beamformers to simultaneously transmit and receive multiple streams over Rician fading channels. The exact first and second positive moments of the residual self-interference (SI), involving the squared norm of a sum of non-identically distributed random variables, are derived in closed-form. The method of moments is hence invoked to provide a Gamma approximation for the residual SI distribution. The proposed theorem holds under arbitrary linear precoder/decoder design, number of antennas and streams, and SI cancellation capability.
