Research on the Power IoT System based on FSK Modulation

This paper focuses on the design of a FSK communication system that operates on the licensed spectrum of 230MHz, specifically tailored for power applications. The system incorporates advanced techniques to improve its performance and efficiency.One key aspect is the utilization of Viterbi decoding at the receiver end, which enables the extraction of soft information from the received signals. This soft information provides enhanced reliability and accuracy in data decoding, leading to improved overall system performance. To further enhance the system's performance, turbo coding is employed. In terms of frame structure design, this paper proposes a FSK communication system that supports multiple frequency access points. This allows for efficient utilization of available spectrum resources and facilitates seamless integration with various local power services. Additionally, a non-scheduling mechanism is implemented to enable flexible and dynamic access to the communication channel without requiring centralized coordination.
