%X This paper considers recognition and estimation of carrier frequency from a time sampled MPSK signal in Automatic Modulation Recognition (AMR), when M and training symbol sequence are unknown. In this case, a new Non-Data-Aided (NDA) carrier frequency estimation algorithm is presented, after recognition of M. The introduction of linear phase unwrapping and high order correlation makes the new algorithm perform better than same traditional NDA carrier frequency estimation algorithms, when frequency offset is large or when the SNR is low. Simulation result shows this fact and it performs well in AMR system.
