<![CDATA[In OFDM-PON system, the synchronization signal is very important. We use synchronization signal to get a whole OFDM signal. Due to the real-time system, we need to get the fast change signal. So get a true signal is very important and very hard. That is to say, we need to design an excellent algorithm to get finish this demand. This is another point of this project. In the paper, the author designed a new algorithm to solve the problems. we use some simulations to compare the performances of different algorithms to get the further understanding. In the experiment, we use more detail algorithms to estimate if it is useful in real-time OFDM-PON system. When the SNR is 10, we can get the synchronization signal correctly.
