通信系统中,由工业设备,电台和其他电子设备等产生的干扰是影响接收信号信噪比的一个重要因素[1]。针对工程实践中信号易受干扰的问题,以chirp信号作为信号源,加入工业跳频干扰噪声,研究消除干扰的方法。在此基础上,提出了一种IIM去干扰算法,在mat-lab上进行了性能仿真,结论表明IIM算法具有良好的去干扰能力。 In communication systems, interference caused by industrial equipment, radio stations and other electronic equipment is an important factor affecting the signal-to-noise ratio of the received signal [1]. Aiming at the problem that the signal is easily disturbed in engineering practice, chirp signal is taken as the signal source, and industrial frequency hopping interference noise is added to study the method of eliminating interference. On this basis, an IIM de-interference algorithm is proposed, and performance simulation is carried out on mat-lab. The conclusion shows that the IIM algorithm has a good capability of de-interference.
