ADAPTIVE DETECTION FUNCTION BASED ON STATISTICAL PROPAGATION CHANNEL ESTIMATION FOR GNSS RECEIVERS

Method and device to decode a GNSS signal in a GNSS receiver (300) comprising a channel decoder (134), wherein the GNSS receiver is configured to:- determine parameters relative to a statistical propagation channel model (301, 302, 303),- compute a statistical channel attenuation from said statistic...

Zusammenfassung:Method and device to decode a GNSS signal in a GNSS receiver (300) comprising a channel decoder (134), wherein the GNSS receiver is configured to:- determine parameters relative to a statistical propagation channel model (301, 302, 303),- compute a statistical channel attenuation from said statistical propagation channel model (310) using the parameters,- compute LLRs from a detection function (333) adapted to the statistical propagation channel model using the computed statistical channel attenuation, and- use the said LLRs to feed the channel decoder.
