Signal processing method and device, communication system, electronic equipment and storage medium

The invention provides a signal processing method and device of a high-speed industrial communication system, a communication system, electronic equipment and a storage medium, and the high-speed industrial communication system is mainly used for solving the problems that a conventional bus in an industrial field is low in bandwidth, cannot bear real-time and non-real-time at the same time, and is complex in network structure. The high-speed industrial communication system can support IPV6 address communication, can support time-triggered industrial control communication, can support TSN, and can support security mechanisms such as white list, deep detection and data encryption. The method comprises a transmitting signal processing method and a receiving signal processing method, and the transmitting signal processing method is used in a transmitting link and comprises the following steps: acquiring a first digital OFDM signal with a baseband sampling rate; performing interpolation filtering on the first digi
