“…We can see that all the PRNs which have C/N 0 in the same range can use the same reference distribution without significant effect on the algorithm. For example, signals in the range [48,49,50,51,52,53,54,55,56,57,58,59] dBHz (e.g., PRN 1, PRN 5, PRN 6 and PRN 10) could use the reference distribution of PRN 5 with limited false alarm rate. However, from the table, we can also realize that the lower the C/N 0 value, the higher the false alarm rate.…”
