Comparison of Experimental & Theoretical BOC(1,1) Autocorrelation
Functions

Theoretical Autocorrelation Function of CL1-C Primary PRN
code |
Theoretical Cross Correlation Function between CL1-B PRN
code and CL1-C Primary PRN code |
Theoretical Autocorrelation Function of CL1-C Secondary PRN
code
|
Experimental Autocorrelation of 1.023 MHz In-Phase
Accumulations after Carrier & BOC Removal (notice peaks at multiples
of 200 msec) |
Soft-Bit/Chip Discrimination Geometry using 250 Hz
Correlations |
Squared-Error Cost as a Function of Candidate PRN Code Start
Times |
Soft Chip Estimates for CL1-C Primary PRN Code
(strong separation implies a negligible chip error probability)
|
GIOVE-A L1 Carrier Doppler Shift Time Histories from Standard PLL that
uses derived CL1-B PRN code and from Ephemerides (the 6.5 Hz offset
from the NORAD prediction may be caused by receiver clock bias)
