Study on the Design of LAS Code in the LAS-CDMA

摘要

The paper mainly studies the designs of LA, LS and LAS codes. Then it makes simulation for theirs auto-correlation functions and cross-correlation functions. Simulation and analysis show that, LAS code has zero cross-correlation in the "zero interference window", and has only an impulse auto-correlation in the "zero interference window", and these excellent features help to eliminate ACI, MAI and ISI, thus it increases the system capacity largely. So it has more large potential than traditional codes.
