This invention discloses an underwater acoustic modem based on STM32 and Raspberry Pi, belonging to the field of underwater acoustic communication technology. Compared with previous modems, this invention improves upon the shortcomings of DSP-based modems, which are characterized by high cost, difficult development, and relatively poor system compatibility; and software-defined radio architecture modems, which are characterized by high hardware cost, high power consumption, and unsuitability for deployment in underwater communication networks. Furthermore, most existing modems cannot simultaneously guarantee communication distance and low bit error rate. This invention utilizes a low-power, low-cost STM32 chip and Raspberry Pi as the core board for modem development. With Raspberry Pi as the software core, it offers faster speed, larger memory, and easier development and expansion. The device size is reduced through a self-designed MCU, meeting the requirements of underwater network nodes. It also employs an adaptive autocorrelation threshold algorithm, enabling the demodulator to adapt to various underwater environments during frame synchronization, while achieving longer communication distances and lower bit error rates.
