Frame Detection and Synchronization for a SIMO Receiver in presence of Doppler Shift for Underwater Acoustic Communications

In underwater acoustic communications, the received signal is strongly affected by Doppler shift due to the relative motion between the transmitter and the receiver. The signal is received compressed or dilated making it hard to detect and synchronize. Therefore, the doppler shift needs to be estimated and compensated. In this article, a new multisensor method to jointly estimate the Doppler shift, detect and synchronize the signal is proposed.
