本人本科的毕业设计,基于Serpent密码的回退N协议的数据传输,希望可供大家参考,谢谢诶！()

qpsk在高斯信道下的仿真，包括误码率和仿真图(Simulation of QPSK in Gaussian channel)

EMW模块说明书 wifi模块 说得很详细(EMW module manual the EMW module manual EMW module manual EMW module manual)

this is simply a report on the fading channel on different modulation scheme

matlab写的ldpc编译码仿真，自己可以该参数看误码率，(matlab ldpc encode decode)

matlab code for qpsk

在TOA测距的基础上，提出了一种三维无线传感器网络节点定位算法，并对其性能进行了分析，给出了算法的时间同步误差和定位误差。最后在现有仿真平台OMNET++的基础上构建三维仿真模块，对算法进行了仿真实现，给出了该算法的定位精度和覆盖率(This paper proposes one three-dimensional localization algorithm based on TOA distance measurement and analyzed the performance of the algorithm calculated time synchronization error and localization error. Finally it constructed three-dimensional simulation modules based on OMNET++ and implemented the algorithm educed the localization precision and coverage.)

说明：  cdma系统的仿真程序,包括cdma各个系统的仿真，可扩展(cdma system simulation program, including all cdma system simulation, scalability)

说明：  详述LDPC码，有DVB_S2中LDPC编解码分析等以及KDH文档。(LDPC code in detail, there are DVB_S2 in the analysis of LDPC codec and KDH document.)

说明：  实现了8PSK的调制，画出了时域及频域信号波形，以及8PSK的星座图。(The 8PSK modulation is realized, and the time domain and frequency domain signal waveforms, as well as the 8PSK constellation diagram are drawn.)
