Title:
AN OFDM TRANSMISSION SYMBOL SYNCHRONIZATION METHOD AND THE SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/003261
Kind Code:
A1
Abstract:
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.
