摘要
由于700 MHz频段清频周期的限制,该频段内5G网络广电系统极易受到同频干扰,进而影响覆盖范围内终端用户的信号接收质量。因此,基于700 MHz频段配置方法原则,详细阐述5G网络广电系统受同频干扰的原理与特点,提出一种基于频域信息的5G广电700 MHz频段抗干扰算法,并对算法的可行性和有效性进行仿真测试。试验结果表明,所提算法能够完成干扰类型的识别与干扰目标的规避等抗干扰措施,具有一定的参考意义。
Due to the limitation of the frequency clearing period in the 700 MHz frequency band,the 5G network broadcasting and television system within this frequency band is highly susceptible to co-frequency interference,which in turn affects the signal reception quality of end users within the coverage range.Therefore,based on the research on the principles of 700 MHz frequency band configuration methods,this article elaborates in detail on the principles and characteristics of 5G network radio and television systems subjected to co frequency interference,proposes a 5G radio and television 700 MHz frequency band anti-interference algorithm based on frequency domain information,and conducts simulation tests on the feasibility and effectiveness of the algorithm.The experimental results show that the algorithm can achieve anti-interference measures such as identifying interference types and avoiding interference targets.It has certain reference significance.
