Optimized Doppler Estimation and Symbol Synchronization for Mobile <i>M</i>-ary Spread Spectrum Underwater Acoustic Communication
In mobile underwater acoustic (UWA) communications, the Doppler effect causes severe signal distortion, which leads to carrier frequency shift and compresses/broadens the signal length. This situation has a more severe impact on communication performance in the case of low signal-to-noise ratio and...
