摘要

本文考虑具有带内全双工(FD)能力的移动辅助用户(SU)。我们研究了SU迁移率和残余自干扰(RSI)对传感性能的影响。主从用户之间的衰落信道被认为是时间选择频率的平坦瑞利衰落信道。RSI信道也假定为瑞利衰落信道。我们解析地导出了虚警和检测概率的封闭表达式。此外，我们还利用能量检测器(ED)分析了接收机的工作特性(ROC)和总误差率(TER)性能。结果表明，感应性能随着二次用户速度的增加和RSI的影响而下降。通过蒙特卡洛仿真验证了结果。

Spectrum Sensing in Mobile Full-Duplex Cognitive Radio

In this paper, a mobile secondary user (SU) having in-band full-duplex (FD) ability is considered. We investigate the effect of the SU mobility and residual self-interference (RSI) on sensing performance. The fading channel between primary and secondary users is considered to be time-selective frequency flat Rayleigh fading channel. The RSI channel is also assumed to be Rayleigh fading channel. We analytically derive the closed form expressions for false alarm and detection probabilities. Moreover we analyse the receiver operating characteristics (ROC) and total error rate (TER) performance using energy detector (ED). The results show that the sensing performance degrades with increase in secondary user’s speed and also due to RSI. The results are verified through Monte Carlo simulations.
