The application of TD-MFM in underwater acoustic communication;

M-ary chaotic spread spectrum Pattern time delay shift coding scheme for multichannel underwater acoustic communication;

UWA communications suffer from interferences due to multi-path,ambient noise and Doppler shift.

However,serious multipath fading and Doppler frequency shift lead to high bit-error-rate of UWA communication.

Narrow channel band,severe multipath interferences and severe channel attenuation have demonstrated the great complexities and difficulties of high-speed UWA communications.
