Research of Mobile Underwater Acoustic Communication of M-Ary Combining FDM and Piecewise-LFM
Aiming at the countering doppler shift, a mobile underwater acoustic communication scheme of M-ary via FDM-PLFM is proposed. The cross-correlation between piecewise linear frequency modulation(PLFM) and traditional LFM signal is analyzed based on the cross-correlation function. Combining with freque...
