Abstract

The influence of the length of cyclic prefix to ML algorithm synchronization performance has been studied. On the basis, an improved algorithm with variable length of cyclic prefix is proposed. The proposed algorithm has better synchronization performance than ML algorithm at low signal to noise ratio.

Keywords
