摘要：
The modified autocorrelation algorithm for synchronizing orthogonal frequency-division multiplexing signals propagating over acoustic underwater communications systems is examined, and analytical estimates of its accuracy are presented. It is demonstrated that the algorithm optimization under multipath channel conditions leads to modified window functions used to calculate likelihood functions. The suboptimal efficient variant of the algorithm based on rectangular windows is proposed.
