摘　　要：文章介绍了利用不同占空比实现信道复用的新型复用技术,即DCDM(占空比复用)技术,分析了其复用与解复用的原理,并利用MATLAB软件设计了DCDM系统的解复用器。为了验证DCDM的可行性,采用Optisystem与MATLAB软件的联合仿真,设计了基于DCDM 3路用户的光纤传输系统,仿真验证了系统的可行性。In this paper,we first introduce a novel multiplexing technology for realizing channel multiplexing i.e.Duty Cycle Division Multiplexing （DCDM）,which realizes multiplexing by assigning each user a different RZ duty cycle.Then we analyze the principles of its multiplexing and demultiplexing and design a demultiplexer using MATLAB.In order to verify its feasibili-ty,we design a fiber-optic transmission system based on DCDM of three users by joint simulation with Optisystem and MAT-LAB.Simulation results verifies the feasibility of the system.
