） Abstract： There are many orthogonal subcarriers in OFDM system,which is sensitive to the timing and carrier frequency offset,so synchronization is particularly important for OFDM system
Reference to IEEE802
11a physical layer frame structure,the algorithm to estimate the timing and carrier frequency offset of the 802
11a system is analyzed and simulated by using the matlab
Simulation results show that the algorithm of synchronization has many advantages: short acquisition time, high sensitivity and wide estimated range,it can be applied to a frame structure with 802
