A receiver (1) of a position-finding system comprises a calculation unit (6, 7, 8) for calculation of a statistical value (.LAMBDA.) on the basis of a received signal, and a detector unit (9) for comparison of the statistical value (.LAMBDA.) with a threshold value (.kappa.) and for determining whether the received signal is a synchronized location signal, an estimation unit (10) for estimation of the Rice factor (K) of the radio link via which the received signal has been transmitted, and a determination unit for calculation of the threshold value (.kappa.) on the basis of the Rice factor (K).
