画包络谱和幅值谱的matlab程序

This is the machine-generated representation of a Handle Graphics object and its children. Note that handle values may change when these objects are re-created. This may cause problems with any callbacks written to depend on the value of the handle at the time the object was saved.(This is the machine-generated representa tion of a Handle Graphics object and its childre n. Note that handle values may change when these objects are re-created. This may cause problem s with any callbacks written to depend on the val ue of the handle at the time the object was saved.)

QPSK的调制解调，跟书上的框图基本如出一辙，希望对大家有帮助。(QPSK modulation and demodulation, the basic block diagram of the book with the same, we want to help.)

《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。此为中文翻译本。(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.)
