我们考虑一个多跳全双工中继（FDR）系统，其中多个全双工解码和转发中继级联连接，以便将信息从源终端转发到目的地终端。由于FDR会在中继站造成额外的“回声”干扰，我们引入了一个参数，该参数可以捕获中继站将传输与接收隔离的能力。当发射功率对于有用信号和干扰信号相同时，该参数被定义为接收的期望信号功率与接收的干扰功率之比，并且被称为“路径损耗干扰比”（PLIR）。对于给定的PLIR值，我们调查的全双工中继，导致最小的中断概率的数量。多跳半双工中继（HDR）的性能也研究了作为一个基准，表明FDR优于HDR，在中断概率方面，足够大的值PLIR。
We consider a multihop full duplex relaying (FDR) system, where multiple full duplex decode-and-forward relays are connected in cascade so as to forward the information from a source terminal to a destination terminal. Since FDR causes additional "echo" interference at the relay, we introduce a parameter that captures the ability of the relays to isolate transmission from reception. This parameter is defined as the ratio of the received desired signal power to the received interference power, when the transmit power is the same for the useful and the interfering signals, and dubbed as quotedblleft path-loss-to-interference ratioquotedblright (PLIR). For given values of the PLIR, we investigate the number of full duplex relays that lead to the minimum outage probability. The performance of multihop half duplex relaying (HDR) is also studied as a benchmark, showing that FDR outperforms HDR, in terms of the outage probability, for sufficiently large values of PLIR.
