Cross Correlation Peak Value of Wideband signals - The Phase and Sample Offset are related but how
To be sure there is no conflation between "phase" and "delay" in the time domain, I refer to a phase shift in time as:
$$y(t) = x(t)e^{j\theta}$$
Whereas a time shift (delay) is ...

GNSS Acquisition in time domain: Why is conjugate of FFT replica used for the mixer?
You remember how convolution of two signals $x(t)$ and $h(t)$ in time domain is equivalent to point-wise multiplication in the frequency domain, $\mathcal F\{x\}(f)\cdot \mathcal F\{h\}(f) = \mathcal ...

GNSS : Code Phase and Carrier Phase Relation
Basically, the only relation is that they're both caused by the distance between transmitter and receiver (and delays, phase shifts).
"Code phase" applies the idea of phase (which is ...

Extracting raw gps messages with GNSS
It's rather straightforward to see the raw data transmitted from any given GPS Satellite, using the details provided in the GPS Signal Specification (for example: see https://www.gps.gov/technical/ps/...
