PURPOSE: A frequency offset estimating method of TR-MUSIC base is provided to prevent performance degradation due to frequency offset estimation considering the changed noise form according to perform EEP in a received signal. CONSTITUTION: An autocorrelation process of EEP(Envelop Equalized Processing) treated received signal is performed. An autocorrelation matrix corresponding to a result signal applying TR-MUSIC(Trimmed Multiple Signal Classification) technique is generated. A signal partial space and a noise partial space are formed by applying decomposition in the autocorrelation matrix. The largest size of frequency is estimated as a frequency offset among a generated frequency spectrum by multiplying signal partial space and noise partial space is estimated. |
