为了满足高可靠的工业通信需求,基于软件无线电的通讯模式成为工业无线通信的发展方向。针对工业的噪声环境,提出了利用经验模态分解对无线通信信号进行分解的滤波算法,利用CCSLink将该算法的Matlab程序传到CCS中,通过编译器生成满足软件无线电平台所需的嵌入式代码,在平台的信号接收端,去除干扰分量,并对分段滤波后的信号进行重构。试验结果表明,该算法有效地解决了工业干扰所造成的无线通信的不稳定性。
In order to meet the demand of high-reliability industrial communication, the communication mode based on software radio has become the development direction of industrial wireless communication. According to the industrial noise environment, a filtering algorithm using EMD to decompose the wireless communication signal is proposed. The Matlab program of the algorithm is transmitted to CCS by CCSLink, and the embedded code that meets the requirements of the software radio platform is generated by the compiler At the signal receiving end of the platform, the interference component is removed and the segmented filtered signal is reconstructed. Experimental results show that this algorithm can effectively solve the instability of wireless communication caused by industrial interference.
