本文对双用户干扰中继信道进行了研究。对该网络的传输方案进行了比较。即压缩转发(CF)和功能解码转发(FDF)。在CF中，中继器通过压缩其观测结果并将其转发给接收器来与用户建立协作。在FDF中，中继器对传输信号的线性组合进行解码，并转发该线性组合。我们将这些方案与译码转发(DF)和IRC中的速率上限进行了比较。结果表明，这些格式的性能优于DF，并且在某些情况下逼近上界。
In this paper, the two-user interference relay channel (IRC) is studied. Transmission schemes for this network are compared. Namely, compress-and-forward (CF) and functional decode-and-forward (FDF) are presented. In CF, the relay establishes cooperation with the users by compressing its observation and forwarding it to the receivers. In FDF, the relay decodes a linear combination of the transmitted signals, and forwards this linear combination. We compare these schemes with decode-and-forward (DF) and with a upper bound on the rates in the IRC. It turns out that these schemes outperform DF, and approach the upper bound for some cases.
