Abstract:

The relations among three parameters of LA code and the relations between the auto-correlation function and the parameter of the LA code are investigated. It is proven that >98 is a sufficiency condition when the auto-correlation function of the LA code in LAS2000+ system is on ideal state. This sufficiency condition is important for the design of LA code and the frame structure of the system in which LA code is used.

Key words: large area synchronous-code division multiple access, auto-correlation function, ajacent cell interference
