Abstract
Long Term Evolution (LTE) cell detecting apparatus includes a secondary synchronization signal (SSS) reference signal generating unit for generating reference signals of all SSSs included in a specific subframe, a memory for storing a reference phase difference sequence with respect to the reference signal of the SSS generated, a Fast Fourier Transform (FFT) operation unit for performing an FFT operation with respect to a received radio signal to output a primary synchronization signal (PSS) and an SSS, a time synchronization acquisition unit for acquiring LTE time synchronization by the PSS output from the FFT operation unit, and a cell detection unit for detecting an LTE cell by the time synchronization information acquired by the time synchronization acquisition unit and a correlation between a phase difference sequence of a received SSS output from the FFT operation unit and the reference phase difference sequence stored in the memory.
