Cyclic Shift Keying Combinatory Spread Spectrum Underwater Acoustic Communication Scheme for Miniaturized AUVs
摘要
Abstract
The communication system of small autonomous underwater vehicles needs to achieve high communication performance based on low power consumption,low complexity and small size platform due to the constraints of the miniaturized platform itself and the complex characteristics of the channel in the restricted waters.To address this challenge,a cyclic shift keying combinatory spread spectrum communication technology scheme is designed based on the cyclic shift keying technology and the combined spread spectrum communication technology.In order to solve the Doppler effect caused by the motion state of the vehicle,the preset frequency offset range Doppler estimation method and low complexity relocation Doppler compensation scheme are designed.The simulation experiment of Doppler estimation and compensation and the water pool communication experiment of the small autonomous underwater vehicle are conducted to verify the effectiveness of the proposed communication scheme and Doppler estimation and compensation method.The proposed cyclic shift keying combinatory spread spectrum communication scheme can effectively improve the transmission rate and stability of underwater acoustic communication based on small size and low resource platform under multi-path channel.关键词
