Abstract

The present application relates to an orthogonal frequency division multiplexing (OFDM) receiver and a method of operating the receiver for performing a cell search. A coarse correlator block is provided to detect one cell out of a plurality of wireless communication cells by determining first correlation values by applying a partial correlation comprising part-wise correlating sample data with each one of a first set of phase-rotated reference sequences and non-coherent combining. The maximum of the first correlation values yields to a cell identifier value. A fine correlator block is provided to estimate a fine time offset value for the one wireless communication cell by determining second correlation values by applying a correlation comprising correlating the sample data with each one of a second set of phase-rotated reference sequences. The maximum of the second correlation values yields to a fine time offset.
