Coarse Frequency Offset Estimation of TD-LTE Based on Spectrum Centroid

Abstract:

Frequency offset brings a great impact on communication, a small amount of which may cause a serious decline in the performance of communication system. So frequency offset estimation has great significance. TD-LTE system is very sensitive to the frequency offset, we propose a method to estimate the integer frequency offset through calculating spectrum centroid. Simulation results show that the algorithm has a good performance and lower complexity compared with some integer frequency offset estimation algorithms based on data-aided.
