Design of low-cost underwater acoustic modem based on MSP430 MCU

Traditional underwater acoustic modem has characteristics of high power consumption, high cost and low transmission rate. So a low cost underwater acoustic modem is designed under guaranteeing the performance of underwater acoustic communication. Based on the principle that"software replace hardware and hardware be highly integrated", the modem solves the current problem of underwater acoustic communication system which only rely on specialized hardware to achieve the modulation and demodulation. Furthermore, the cost of underwater acoustic modem is reduced because the control is easy to implement and elimination of the cumbersome external circuit. Several properties of the modem show that the design has a good performance in data transmission rate and reliability for underwater wireless sensor networks.
