Abstract
A sampling frequency offset (SFO) estimation and compensation method based on frequency domain correlation of long training symbols for orthogonal frequency division multiple access passive optical network (OFDMA-PON) is experimentally demonstrated, which shows excellent performances in transmissions of continuous- and burst-mode. For continuous-mode transmission under a certain SFO, the proposed scheme can perform effectively in a wide received optical power (RoP) range from â8Â dBm to â2Â dBm and has high estimation veracity and a large applicable range as large as 100Â ppm at a certain RoP. Similar behavior is also demonstrated under burst-mode transmission with tiny performance degradation caused by the fact that the algorithm needs time to reach a stable status of synchronization.
