Abstract
For the contradiction between accuracy and data size, this paper introduces an improved estimation algorithm of symbol synchronization based on the maximum mean power estimation algorithm. A Deslauriers-Dubuc interpolation filter is used in the improved algorithm. Analysis of experimental results showed that the estimation algorithm proposed in this paper not only improves the accuracy of estimate, but also has a smaller calculation that facilitates the implementation of low-complexity.
