Digital Signal Processing Technology in the Communication Field under the Background of the Internet of Things

With the popularization of the Internet and the rapid development of new technologies such as artificial intelligence, cloud computing, and the Internet of Things(ITS), the explosive growth of data traffic puts forward higher requirements for transmission performance. In order to meet the ever-increasing demand for capacity and cope with the ensuing crisis, the application of digital signal processing technology in the communications field is imperative. With the development of high-speed integrated circuits and digital signal processing algorithms and other technologies, high-speed digital signal processing has become increasingly mature, and ITS has become one of the global research hotspots. The country is also strategically advancing the research on ITS. This article mainly uses the experimental analysis method to explore whether the application of digital signal processing technology can provide a new idea for the development of the communication field in the context of ITS. In the experiment, this article analyzes the OPA multiplexing mode demodulation energy and crosstalk energy, and analyzes the changes of the bit error rate under different communication rates and different communication distances. According to the experimental results, OPA multiplexing transmission has a certain degree of stability. The combination of OPA mode multiplexing technology and traditional systems can provide more possibilities for building communication networks with higher capacity systems in the future. As the communication rate and communication distance increase, the bit error rate will increase accordingly. Therefore, this article studies the application of digital signal processing technology in the communication field under the background of ITS, which has huge application potential and research value.
