Claim:
1. A method, comprising: receiving a signal comprising a two-dimensional signal pattern in a time-frequency representation using a receiver circuit, the two-dimensional signal pattern comprising a synchronization signal at a first predetermined position in the two-dimensional signal pattern and one or more cell-specific reference signals at one or more second predetermined positions in the two-dimensional signal pattern; determining a first cell identification information using a processor circuit based on a first threshold criterion with respect to a correlation of the synchronization signal; determining a second cell identification information using the processor circuit based on a second threshold criterion with respect to a frequency-time transformation based on the one or more cell-specific reference signals to obtain a time-domain signal using a frequency-time transformation processing circuit; and detecting a true cell or a ghost cell by comparing a first time range of the first cell identification information with a second time range of the second cell identification information, wherein a true cell is detected when the second time range of the second cell identification information is within or is overlapping the first time range of the first cell identification information.
