Abstract (en)

[origin: WO0142810A1] The present invention discloses a method for determining synchronisation of a signal received in a global positioning system receiver and transmitted by a global positioning system satellite, said method comprising: transform coding said received signal so as to transform said received signal from time domain to frequency domain coefficients, selecting from said frequency domain coefficients those frequency domain coefficients contributing substantially zero energy, deriving from the selected coefficients an estimation indication of in-band noise.
