Frequency Offset Estimation Based on Fixed Point Algorithm Using Looking-Up Table in OFDM
Frequency offset estimation is one of the key technologies in OFDM system,the estimation precision and efficiency directly influence the performance of the OFDM system. Under the restriction of the DSP storage space and frequency offset estimation precision,a new frequency offset estimation algorithm using look-up table is designed in this paper,which fulfills real-time demand and dramatically reduces the DSP storage requirements and fixed-point accumulative error.
