Abstract :
An iterative phase compensation algorithm is presented to recover carriers for underwater acoustic communications in this paper. The joint equalization and phase compensation are iteratively implemented. In a new iteration, the second-degree polynomial is used to fit a phase sequence. The performance of new algorithm is analyzed with simulations. The results show that the equalizer with the phase compensation is able to effectively resist the channel phase rotating introduced by frequency offset.
