An all-optical regeneration scheme for DQPSK and QPSK signals using phase-sensitive amplifiers (PSAs) is studied and its effectiveness is investigated through numerical simulations. By leveraging the ability of PSAs to provide phase and amplitude regenerative amplification, we show significant simultaneous suppression of both phase and amplitude noises of (D)QPSK signals under optimized conditions. The reduction in the phase noise variance of a noise-corrupted DQPSK signal obtained by one such regenerative amplification can be as large as 5.5 folds, showing its good potential for distributed optical regeneration of (D)QPSK signals.  2008 Elsevier B.V.

CMDA 系统中下行链路的通信与仿真 MATLAB仿真实现(CMDA Simulation)

一款利用matlab编写的射线追踪程序，易改易用。(The installation of TTBOX is relatively simple. All you have to do is to create some directories and tell MatLab, where TTBOX is. if it does not already exist, create a directory matlab within your home directory. Copy the TTBOX directory into the matlab directory if it does not already exist, create a file startup.m within the matlab directory Insert the following lines into startup.m: basepath= This should be the path to your home directory! addpath([basepath filesep matlab filesep ttbox ],1) addpath([basepath filesep matlab filesep ttbox filesep support ],1) execute startup within the MatLab command window. MatLab is now ready to execute TTBOX routines. The startup-script will be executed automatically upon start of MatLab. In order to read the online documentation, you have to browse to the doc directory and open the ttbox/doc/ttbox.html file with your web browser (it is recommended to set a bookma)

实现了无线通信中需要使用的信道模型，分析各种模型下的输入信号后的仿真和分析(On the basis of the study in multi-path propagation theory, characteristics and mathematics models of wireless channels, and the analysis of references from both domestic and international realm, this thesis will generalize the detailed classification of wireless mobile communication channels, and the typical small-scale fading modules (Rayleigh fading and Rice fading), which the signals has encountered while transmitted in communication channels. )
