本文研究了瑞利衰落信道中干扰抑制双向传输协议的性能。以封闭形式推导了三相双向中继(3P-TWR)协议中断概率的新下界和误码率的近似表达式。这些表达式对于实际系统中使用的任意信噪比、同频干扰数和大多数调制格式都是有效的。然后，基于中断概率和误码率的渐近表达式，对直接传输(DT)、两相双向中继(2P-TWR)和3P-TWR三种双向传输协议的性能进行了比较研究。在理论结果的基础上，得到了不同协议相对性能的直接信道强度(方差)门限和目标速率门限，并分析了终端和中继端干扰对相对性能的影响。研究结果为在实际干扰受限场景下如何在衰落信道、所需数据速率和调制格式的基础上选择合适的双向传输协议以优化系统性能提供了关键的见解。仿真结果验证了理论分析的正确性。
This paper investigates the performance of interferencelimited two-way transmission protocols in the Rayleigh fading channels. New lower bound of outage probability and approximate expression of bit error rate (BER) for three-phase two-way relaying (3P-TWR) protocol are derived in closed-form. These expressions are valid for arbitrary signal-to-noise ratio values, numbers of co-channel interferers and amajority ofmodulation formats employed in the practical system. Then a comparative study is developed for the performance of three two-way transmission protocols, i.e., direct transmission (DT) protocol, two-phase two-way relaying (2P-TWR) protocol and 3P-TWR protocol based on the asymptotic expressions of outage probability and BER. On the basis of the theoretical results, the thresholds on the strength (variance) of direct channel and target rate for the relative performance of different protocols are obtained and the effect of interferences at the terminal and relay on the relative performance is analyzed. The results present key insights on how to choose proper two-way transmission protocol with the knowledge of fading channels, required date rate and modulation format to optimize the system performance in the practical interference-limited scenarios. Simulation results are presented to validate the theoretical analysis.
