Research on interference suppression method for carrier communication process of Internet of Things terminal equipment

文章利用现有方法抑制载波通信过程的干扰时,难以有效分离干扰信号。为此,文章设计了新的物联网终端设备载波通信过程干扰抑制方法。文章通过引入优化后的小波阈值方法,对物联网终端设备载波通信进行去噪处理;采用独立分量分析分离不同信源的通信信号;按照信道编码、中频调制以及调频流程,对载波通信干扰进行批量抑制;通过连接收发通道与重建通道,实现通信传输。实验表明:新方法可以有效分离原始信号中的干扰信号,提高通信质量。

It is difficult to effectively separate interference signals when using existing methods to suppress interference in carrier communication processes.Therefore,a new method of interference suppression in carrier communication of IoT terminal equipment is designed in this paper.In this paper,the optimized wavelet threshold method is introduced to denoise the carrier communication of IoT terminal equipment.It uses independent component analysis to separate communication signals from different sources and batches suppression of carrier communication interference according to channel coding,intermediate frequency modulation,and frequency modulation processes.By connecting the transmission and reconstruction channels,communication transmission is achieved.The experiment shows that the new method can effectively separate interference signals from the original signal and improve communication quality.
