Radiolocalization receiver having a plurality of correlation taps, and including a module of cross-correlation detection in which spurious correlation terms are detected by statistical analysis of the frequencies of the candidate peaks. The system can restrict further integration to those taps whose frequency is outside the cross-interference signal, or trigger new acquisition of different space vehicles, upon detection of a cross-interference situation.

GNSS receiver with cross-correlation rejection

The invention consists of a barometric pressure sensor, coupled to a processor for recording changes in the pressure over time, this is coupled to a GPS device providing an accurate measurement of the altitude which allows for the barometric pressure measurements to be normalized, typically to mean sea level. Once the measurements have been normalized the effects of the vertical motion of the sensor are effectively removed and the resulting trend shows the absolute atmospheric pressure which can then be used for weather prediction.

Weather prediction system

Systems, methods and devices for signal processing are presented. In particular, methods for the detection of signals in CDMA-based systems are presented, together with corresponding devices. These methods provide more efficient use of correlation resources through proper identification of candidate signal peaks and may include performing at least one pre-detection stage and performing at least one distillation stage.
