<p>There is disclosed a Long Term Evolution (LTE) cell detecting apparatus in a multi-cell environment that may efficiently detect an LTE cell even in a multi-cell environment where interference occurs between adjacent cells. The LTE cell detecting apparatus includes a secondary synchronization signal (SSS) reference signal generating unit (40) for generating reference signals of all SSSs included in a specific subframe, a memory (60) for storing a reference phase difference sequence with respect to the reference signal of the SSS generated by the SSS reference signal generating unit (40), a Fast Fourier Transform (FFT) operation unit (10) 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 (20) for acquiring LTE time synchronization by the PSS output from the FFT operation unit (10), and a cell detection unit (30) for detecting an LTE cell by the time synchronization information acquired by the time synchronization acquisition unit (20) 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 (60).</p> |
