AN OFDM TRANSMISSION SYMBOL SYNCHRONIZATION METHOD AND THE SYSTEM THEREOF

摘要

An OFDM transmission symbol synchronization method includes the following steps: an orthogonal frequency division multiplexing OFDM transmission module receives a synchronization signal; the OFDM transmission module synchronizes the OFDM symbols transmitted by each line according to the synchronization signal and sends them. An OFDM transmission symbol synchronization system is provided. The lack in the prior art is overcome. By using the scheme that the synchronization signal is transmitted to the OFDM transmission device after the synchronization signal generator generates the synchronization signal and the OFDM transmission module synchronizes the OFDM symbols transmitted by each line according to the synchronization signal and sends them, the problem of the OFDM symbol synchronization is solved and the performance of the DSM is exerted optimally.
