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.

設計出擴展的Large area Synchronization地址碼(LS碼)——Daoben Lab地址碼(DBL碼)。

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碼、LS碼和LAS碼的構造方法,然后對傳統(tǒng)CDMA和LAS-CDMA的系統(tǒng)容量、頻譜效率和傳輸可靠性進行了探討和比較,表明LAS碼及LAS-CDMA是新型的重要的技術。

The capacity of MIMO DS-CDMA based on the LS codes proposed by the professor D.

在多碼檢測的情況下,李道本教授發(fā)明的LS碼多天線CDMA系統(tǒng)比Walsh碼和Gold碼的多天線系統(tǒng)有更大的系統(tǒng)容量,后兩者在大的信噪比(20dB)時候均有平臺效應;在采用多用戶檢測時它們的容量幾乎相同。

LS code based on the complementary structure is used to Spread Spectrum(SS) with the characteristic of Zero Correlation Window(ZCW).

LS碼是一種基于互補結構的具有零相關性質的擴頻地址碼,有著優(yōu)良的抗干擾性能,越來越受到人們的關注。
