Abstract
A multiple carrier frequency offsets (CFOs) estimation algorithm for MIMO-OFDM systems based on multiple signal classification (MUSIC) algorithm is proposed in this paper. The structure of training sequence (TS) and sub-carrier-band method is also described. Method of spectral peak searching by major step and minor step could improve estimation precision and reduce calculation. At the same time, average spectral function can reduce the effect of random peak. Theoretical analysis and simulation results show CFOs estimation MSE and BER performance of system at different SNR.
