Sentence examples for code phase from inspiring English sources

Figure 1 FFT-based parallel code phase search.

The number of code phase search is variable: By setting the channel parameters, the number of processing points and the number of code phase slips can be controlled, in order to achieve a variable number of code phase search.

where n l is the incoming signal's code phase, m l is the PRN code's code phase, and Δ f l is the residual frequency offset.

Therefore, calculating E and L is the key to code phase alignment.

The criterion for successful control seizure is as follows: the distance between the code phase of the authentic signal and the code phase of the receiver local replicate signal exceeds 1 + d; the distance between the code phase of the spoofing signal and the code phase of the receiver local replicate signal is less than 1+d.

In the simulations, for simplicity, the code phase has been kept constant at 928.125 chips.

Increase the code phase difference between the two signals by 0.01 chip; reset the power difference to 0, and repeat step 2 until the code phase difference is equal to 1+d.

The code phase difference between the authentic signal and spoofing signal is gradually adjusted to separate the two signals.

Once acquisition is achieved, a rough estimate value of the code phase and Doppler can be obtained.

The combination of search in the two dimensions for the code phase and the Doppler shift is called acquisition.

An error of ±1 chip in the code phase results in an error of 300 m in pseudorange.
