A receiver apparatus (100) for determining a correlation value of a predetermined repetitive chip sequence in a receive signal (115), the chip sequence having a chip sequence duration and a chip sequence duration cycle. The receiver apparatus (100) comprises a receive unit (110) for receiving the receive signal (115) and a segmenter (120) for providing receive signal segments from the receive signal, two receive signals representing the same chip sequence in different repetition cycles and having at least one repetition cycle time spacing. The receiver apparatus (100) further comprises a frequency corrector (130) for determining sets of frequency corrected receive signal segments based on sets of correction frequencies, the correction frequencies being based on the chip sequence duration and the chip sequence repetition cycle. The receiver apparatus further comprises a chip sequence generator (140) for generating the predetermined chip sequence and a correlator (150) for correlating the predetermined chip sequence with the frequency corrected receive signal segments of a set to obtain a set correlation value. The receiver apparatus (100) further comprises a selector (160) for selecting one of the set correlation values meeting a predetermined condition as the correlation value. |
