Open publisher page 0 citations

Abstract

Orthogonal Frequency Division Multiplexing(OFDM) technology is an efficient modulation technology.The basic idea is to distribute the high-speed data stream to orthogonal sub-carrier,and the synchronization is a key issue for OFDM technology.Gives OFDM system model,and analyses the synchronization issues specifically.It also gives the description to carrier frequency synchronization algorithm,and simulates CP-based synchronization algorithms.The result shows that the method has better ability to get the right frequency.It also shows that the CP method has less errors.
