Evaluation of C/N estimators performance for GNSS receivers

WebAs in GPS, CDMA usually involves a narrow band message multiplied by a wider bandwidth PRN (pseudorandom noise) signal. The increased bandwidth is wider than necessary to broadcast the data information and is called a spread spectrum signal. As you have read, these PRN codes are attached to the GPS carrier by changes in phase. WebWe compare the performance of the STFT-TFF and FLOSTFTTFF methods; the results show that the performance of the FLOSTFT-TFF method is better than the STFT-TFF …
