DBL access codes are generated from the left or right kronecker product of the LS codes and the extending matrix,and are called DBL left-product codes and DBL right-product codes,respectively.
设计出扩展的Large area Synchronization地址码(LS码)——Daoben Lab地址码(DBL码)。
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.
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。
The capacity of MIMO DS-CDMA based on the LS codes proposed by the professor D.
在多码检测的情况下,李道本教授发明的LS码多天线CDMA系统比Walsh码和Gold码的多天线系统有更大的系统容量,后两者在大的信噪比(20dB)时候均有平台效应;在采用多用户检测时它们的容量几乎相同。
