McWiLL（multi-carrier wireless information local loop，多载波无线信息本地环路）是集智能天线、CS-OFDMA、增强零陷、信道跟踪和预测、动态信道分配、频空联合检测等核心技术为一体的宽带无线通信系统。为此，介绍了McWiLL系统在配电网通信中应用的测试情况，重点在于McWiLL系统的覆盖面、业务容量和业务承载能力。基于中低压配电网的特点及其对通信的...
Multi-rate transmissions on spectral amplitude coding optical code division multiple access system using random diagonal codes
optical code division multiple access (OCDMA) bit error rate (BER)
2011/5/6
In this paper, we study the use of a new code called random diagonal (RD) code for spectral amplitude coding (SAC) optical code division multiple access (OCDMA) networks, using fiber Bragg-grating (F...
Experimental Demonstration of a Hybrid 1/2-dimentional En/Decoding Optical Code Division Multiple Access System
Hybrid coding fiber bragg grating (FBG) optical code-division-multiple-access (O-CDMA)
2016/12/2
A hybrid 1D/2D en/decoding O-CDMA system is proposed to support multiple bit rates. To the best of our knowledge, a hybrid O-CDMA system with 2.5Gb/s (OC-16) and 155Mb/s (OC-3) transmission along the ...
