The present disclosure provides various methods and devices for suppressing cross-correlation effects in positioning signals. When there is a power imbalance between a weaker positioning signal and an interfering positioning signal, and certain Doppler offsets exist, cross-correlation may make it difficult to acquire the weaker signal. However, a receiver may use the transmit signal spectrum of the interfering signal to identify frequency bins which contain a lower power for the transmitted interfering signal. The receiver then emphasizes the identified frequency bins in the detection of the desired positioning signal.
