Analysis of Correlation Characteristics of 10230 Period PRN Code using Concatenated Gold Code

摘要

Analyze and present the correlation characteristics of 10230 length PRN codes generated by concatenating 1023 length gold codes. The proposed scheme consists of two code selection processes. The first code selection process is selected through auto-correlation power limitation, and the second code selection process consists of a code selection process that limits the cross-correlation power between the selected codes in the first process. In the proposed technique, a GPS CA code generator was used to generate a gold code with a length of 1023. We could select 16 codes satisfying auto-correlation power -27 dB and cross-correlation power -26 dB limitation through 10230 PRN codes concatenated with the generated gold codes. The proposed scheme satisfies the best length condition in terms of the cross-correlation power of the Gold code, so it is expected that the possibility of acquisition of the error signal by the power difference between the signals can be reduced.
