Phase Offset Compensation Algorithm Simulation of OFDM

摘要：

The reason of the phase offset in the OFDM system is analyzed in this paper and a method correcting the offset by using the information of pilots inserted in the OFDM frame was proposed. then the algorithm including simple phase compensation and pilot frequency phase compensation were simulated, the result shows that the algorithm proposed in this paper can correct the star map to a scope that can decode the star map correctly and comparing to the simple compensation, it can reduce the bit error ratio(BER). Finally the different effects to the symbol error rate by using the different pilot frequency numbers have simulated, including 50 pilot frequency and 100 frequency inserted in the OFDM data frame averagely, the result shows that that the more we inserting the pilot frequency symbols, the better systems estimating performance under low SNR.
