Magnetic induction channel capacity analysis under frequency splitting phenomenon

Research the frequency splitting characteristics of the magnetic induction communication system in a strong coupling state to increase the system bandwidth and channel capacity, thereby increasing the transmission rate. First, model to the magnetic induction communication system, analyze the influence of different circuit parameters on the trough position, trough number and trough amplitude of the path loss when frequency division occurs; Then use the multi-channel communication channel generated by frequency splitting to analyze the available bandwidth and path loss; finally calculate the channel capacity.Theoretical analysis and simulation results show that the frequency splitting produced by the magnetic induction communication system can effectively expand its channel capacity, thereby improving the transmission efficiency of the system.
