Design of double-weight code for synchronous OCDMA systems with power control被引量:2
《Chinese Optics Letters》2014年第11期40-44,共5页陈富军 罗风光 冯刚 李斌 贺成 
supported by the National"863"Program of China(No.2012AA011301);the National"973"Program of China(No.2010CB328302)
Double-weight optical code division multiple access(OCDMA) systems are proposed for studying differentiated quality-of-service transmission. Based on quadratic congruence code(QCC), we construct a one-dimensional ...

Spectral efficiency analysis of OCDMA systems
《Chinese Optics Letters》2009年第3期183-185,共3页闫辉 邱昆 凌云 
supported in part by the National Natural Science Foundation of China (No. 60572008);the National "863" Program of China (No. 2006AA01Z241)
We discuss several kinds of code schemes and analyze their spectral efficiency, code utilizing efficiency, and the maximal spectral efficiency. Error correction coding is used to increase the spectral efficiency, and ...
