Abstract
The invention relates to a receiver in a position-finding system, having a calculation unit for calculating a statistical value from a received signal, and a detector unit for comparing the statistical value with a threshold value and for determining whether the signal is a synchronized position-finding signal. The system also includes an estimation unit for estimating the quotient of the signal-carrier power and the noise-power spectral density of the signal, and a determination unit for threshold-value determination from the estimated quotient.
