Receiver for receiving e.g. global positioning system signal, of satellite in e.g. global navigation satellite system, has noise compensation units to remove, from outlet of correlator, linear combination of outputs of other correlators

摘要

The receiver has correlators (6-1-6-3) configured to realize correlations of received signal with replicas of an expected signal shifted temporally from each other. An acquisition unit (7) is configured to determine a correlation peak and to retain, among the correlators, control correlators (P, Epower1/2, L power1/2) centered on the correlation peak. Noise compensation units (8, 9) are configured to remove, from an outlet of one of the correlators, a linear combination of outputs of other correlators. An independent claim is also included for a method for reducing a noise disturbing reception of a broad band spectrum spreading signal.
