Research On Decodign Technology For Micro-power Consumption Under Water Acoustic Remote Control System

With the development of underwater acoustic communication technology and digital signal processing technology,the application of underwater acoustic remote control system is widespread in underwater acoustic experiment,ocean development,underwater acoustic communication and underwater weapons.For the device that should be put underwater longtime,such as submarine mine,under water measurement device,power consumption is an important parameter except for communication quality.Designing a underwater acoustic remote control system put underwater longtime is not only saving human and material resources but also helping improve system reliability.This dissertation is based on the above ideas,through the analysis of underwater acoustic remote control theory and rational choice of system solutions,achieved to reduce power consumption requirements.Especially in the frame synchronization signal demodulation,the field will be the use of FM radio signal demodulation method is applied to underwater acoustic remote areas,to resolve the past method due to the use of energy testing or correlation detection methods led to the selection of the device a great power problem.Using the MSP430 microcontroller to achieve frame synchronization signal demodulation largely reduced power consumption of acoustic remote control system.
