Basic simulation of Dynamic Spectrum Acce-Basic simulation of Dynamic Spectrum Access

本文详尽的介绍了认知无线电中的动态频谱分配技术，有助于初学者的学习-The article introduces the cognitive radio technology, the dynamic spectrum allocation to the beginners

版块是用香浓定理来述说扩频通信时传播原理。并用MATLAB的编程软件去建立一个直接扩频的仿真模型的，在排除其他因素的情况下可以观察曲线和动态图去分析直接扩频的可靠程度-Section in aromatic theorem is used to declare the spread spectrum communication transmission principle. With MATLAB programming software to build a simulation model
