Reacquisition method of a CDMA modulated satellite signals and receiving apparatus implementing the method
Abstract:
Acquiring a satellite signal, by, receiving a CDMA-modulated signal; generating a plurality of CDMA-type test signals comprising a reference test signal having a first chip duration, and a plurality of test signals delayed/anticipated of a corresponding time offset from the respective test reference signal, less than the chip duration; calculating correlations between the CDMA-modulated signal and the plurality of test signals for obtaining a plurality of correlation results; selecting, based on the correlation results, acquisition parameters associated to a candidate satellite signal; acquiring or rejecting the acquisition parameters selected based on the correlation results.
