Research on micro power wireless communication system based on OFDM technology

The mainstream modulation technology of micro power wireless communication chip is (G) FSK ((Gauss) Frequency Shift Keying), but this technology has the defects of wide bandwidth occupation, low bandwidth utilization and low sensitivity. To solve this problem, improve the performance and frequency band utilization of micro power wireless communication system, and realize the high reliability and real-time of communication, a micro power wireless communication system based on OFDM (Orthogonal Frequency Division Multiplexing) technology was proposed in this paper, which can effectively improve the reliability, real-time and receiving sensitivity of meter reading. The test results show that this method meets the functional and performance requirements of state grid interconnection.
