I'm reading about PSC (primary synchronization code) in UMTS. It is a so-called Golay sequence. It is said it has a good aperiodic auto correlation properties.
What does it mean (in terms of aperiodic)?
What is the difference between good periodic/aperiodic auto correlation properties?
How does it differ from good cross-correlation properties?
The questions ares not about PSC in UMTS in particular. It's rather about terminology
Thanks in advance.
