The research on synchronization technology of OFDM system based on pilot

Yaoqun Huang, Yuan Bian

Abstract

For the problem of OFDM system demanding synchronization strictly, proposes a synchronization algorithms for OFDM system based on pilot, using the preamble to fast and accurate acquire signal, establish synchronization in the limited time, and using pilot to track synchronization information. Application of MATLAB for system modeling and simulation by analyzing the key techniques of OFDM, the results show that this algorithm can overcome the adverse effects of Gaussian noise and frequency offset effectively, eliminate frequency offset, and less computation.
