Abstract

In order to realise the transmission of underwater data, this paper proposes an improved 2FSK modulation method based on field programmable gate array (FPGA) and PWM modulation technique implementation. The method generates a sinusoidal signal by writing a Verilog language on vivado software, and performs conventional 2FSK modulation on this signal, and finally the signal after 2FSK modulation is PWM modulated, which enhances the immunity of the signal to interference.
