1.0 Definition and Generation
The Long PN Code
The Long PN Code is generated by a 42-stage Linear Shift Register. Therefore, the maximum length of the Long PN Code is:
- L=2N-1 = 242-1=4.4 x 1012=4.4 trillion chips
- The Long PN Code also runs at a speed of 1,228,800 chips per second.
- This yields a repetition cycle of 4.4 x 1012/1,228,800=41-42 days.
