针对通信侦查课题，通过已知先验知识和截获信号，进行找出同步序列，匹配滤波，校正频偏和相偏，均衡，解交织，译码，恢复出原序列，最终得到的序列与原序列作对比得到误码率为0(Investigation subject for the communication, by known a priori knowledge and intercepted signal conducted to identify the synchronization sequence, the matched filter, correcting frequency offset, and phase deviations, balanced, deinterleaving, decoding, to recover the original sequence, the resulting sequence with the original sequence compared error rate is 0)

一个很小和天线计算程序,我觉得非常实用,发上来与大家分享()

ASK系统的设计与仿真，相干解调及误码率的计算(Ask system design and simulation of coherent demodulation and the calculation of the bit error rate in English)

mpls tp oam frame work from ietf. very usefull

DFTS--OFDM 仿真程序 包括详细的PAPR仿真 均可运行 (DFTS- OFDM simulation program should include a detailed simulation of the PAPR can be run)

说明：  在matlab环境下,仿真基于循环平稳特征检测的频谱感知,(Spectral sensing based on cyclic stationary feature detection)

基于OPNET的卫星通信程序，为Opnet网络仿真书籍的实例(based satellite communications procedures for Opnet Network Simulation examples of books)

说明：  实现20m双绞线有线通讯，一端控制另一端小灯亮暗，反过来，一端发送字符，另一端显示浮点数(Realize 20m twisted-pair cable communication, one end controls the light of the other end, conversely, one end sends characters, the other end shows floating-point numbers.)

说明：  实现了64qam，16qam和QPSK的误码率仿真(The bit error rate simulation of 64qam, 16QAM and QPSK is realized.)

说明：  近两天由于研发需要OPNET这个仿真软件，同时要求可以支持wimax仿真模型，对该仿真软件的研究还需要继续进行 好不容易在网络上找到了最新版的OPNET 14.5的软件，但是安装的确出现了很大的麻烦，最后通过查阅网络上对之前版本安装的经验解决了安装过程中的问题，因此将这些分享给大家： (Almost two days because of this R &amp D needs OPNET simulation software, also required to support wimax simulation model, the simulation software is also the need to continue the network finally found the latest version of the OPNET 14.5 software, but certainly there was an installation much trouble, and finally access to the network through the installation of the experience of the previous version to solve the problems during the installation process, it will share all of these:)
