A Study of OFDM Synchronization Algorithm Based on Coaxial Cable Operating at Gigabit

摘要：

When OFDM is applied at a Gigabit coaxial cable carrier communication system, small range of frequency offset estimation and poor frequency offset estimation accuracy have become main obstacle at symbol synchronization process. The paper designs a joint time-frequency symbol synchronization algorithm combining training sequence and the classical maximum-likelihood (ML) synchronization algorithm. In the multi-path channel, the algorithm can ensure that the symbol synchronization position is properly detected, improves the frequency offset estimation accuracy and expands range of frequency offset estimation (-0.8 to 0.8). The algorithm can be widely applied in a variety of coaxial cable communication system.
