Abstract

Compared with short-distance data transmission, long-distance data trans-mission receives data with relatively smaller amplitude and greater power interference, which poses challenges for data demodulation. This paper first analyzes the data interference received during long-distance transmission and determines the interference signal frequency. Secondly, based on the frequency and amplitude of the effective data and the frequency and amplitude of the interference data, an data demodulation scheme is designed to suppress interference and amplify the effective data. Finally, a physical platform is built. Under the conditions of a 50 cm diameter coil and a transmission distance of 1 m, the correct demodulation of data is achieved at an output power of 135 W, with an data transmission rate of 4800 bps.
