A receiver apparatus (100) for determining a correlation value of a prede termined repetitive chip sequence in a receive signal (115), the chip sequen ce having a chip sequence duration and a chip sequence duration cycle. The r eceiver apparatus (100) comprises a receive unit (110) for receiving the rec eive signal (115) and a segmenter (120) for providing receive signal segment s from the receive signal, two receive signals representing the same chip se quence in different repetition cycles and having at least one repetition cyc le time spacing. The receiver apparatus (100) further comprises a frequency corrector (130) for determining sets of frequency corrected receive signal s egments based on sets of correction frequencies, the correction frequencies being based on the chip sequence duration and the chip sequence repetition c ycle. The receiver apparatus further comprises a chip sequence generator (14 0) for generating the predetermined chip sequence and a correlator (150) for correlating the predetermined chip sequence with the frequency corrected re ceive signal segments of a set to obtain a set correlation value. The receiv er apparatus (100) further comprises a selector (160) for selecting one of t he set correlation values meeting a predetermined condition as the correlati on value.
