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(shè)計(jì)出擴(kuò)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(gòu)造方法,然后對(duì)傳統(tǒng)CDMA和LAS-CDMA的系統(tǒng)容量、頻譜效率和傳輸可靠性進(jìn)行了探討和比較,表明LAS碼及LAS-CDMA是新型的重要的技術(shù)。
The capacity of MIMO DS-CDMA based on the LS codes proposed by the professor D.
在多碼檢測(cè)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(shí)候均有平臺(tái)效應(yīng);在采用多用戶檢測(cè)時(shí)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(bǔ)結(jié)構(gòu)的具有零相關(guān)性質(zhì)的擴(kuò)頻地址碼,有著優(yōu)良的抗干擾性能,越來(lái)越受到人們的關(guān)注。
