Research on Synchronization Algorithms of OFDM Reliability Engineering

Orthogonal frequency division multiplexing is an efficient modulation technology, its basic idea is to distribute the serial high-speed data stream to the quadrature sub-carriers, and to transmit parallel. The synchronization is the key problem in OFDM reliability engineering. In this paper, OFDM reliability engineering model is provided, the synchronization problem is analyzed in details, the description of the algorithms of carrier frequency synchronization and timing synchronization is presented, and the simulation based on CP synchronization algorithm is also made. The simulation results show that OFDM reliability engineering has good frequency acquisition ability and smaller errors.
