《通信系统仿真原理与无线应用》系统地介绍通信系统的设计、分析和仿真方法，还提供了大量极具参考价值的仿真实例。《通信系统仿真原理与无线应用》的全部仿真程序都是采用MATLAB编写的。这不仅方便读者理解仿真的实现过程，还允许读者修改或使用这些代码段来进行自己的仿真开发。章后提供了大量的参考文献和经过精心设计的各类练习题，方便教学。 此为英文原版书籍(Principles of Communication Systems Simulation with Wireless Applications is a hands-on, example-rich guide to simulating wireless communications systems. The first book to present complete MATLAB simulation models for predicting the impact of design changes, it treats every aspect of simulation: sampling, signal and system representations, filters, noise, Monte Carlo simulation, postprocessing, nonlinear and time-varying systems, waveform and discrete channels, co-channel interference, and more. It includes four detailed case studies.)

介绍了喷泉码中LT 码的编码译码过程，提供了详细的MATLAB 仿真代码和说明. 通过对三种不同度分布的LT 码进行性能仿真，并对仿真结果进行了分析，同时也对LT 码和Raptor 码进行了适当的比较.(Encoding of LT codes decoding process of fountain codes, and provide a detailed MATLAB simulation code and description. Performance simulation, and the simulation results are analyzed by the distribution of three different degrees of LT code, as well as the LT code Raptor codes proper comparison.)
