摘要
LAS码由于具有"零相关窗"或"干扰自由窗",目前受到高度重视。首先分析了LA码、LS码和LAS码的构造方法,然后对传统CDMA和LAS-CDMA的系统容量、频谱效率和传输可靠性进行了探讨和比较,表明LAS码及LAS-CDMA是新型的重要的技术。
LAS codes are highly valued currently for their "ZCZ" or "IFW". This paper first analyzes the ways for constructing LA codes, LS codes and LAS codes, and then makes a survey and comparison on the system capacity, spectral efficiency and the transport reliability, All this indicates that LAS codes and LAS-CDMA are new important technologies
