录制一段噪声，利用matlab对该材料进行声音的频谱分析。(Record a noise, the use of the material to matlab sound spectrum analysis.)

CDMA EQULAISER FOR COMMUNICATION STUDY

说明：  软件管理课程的前三章介绍，主要讲了一些模型，并进行分析(ruanjianguanglikechengdeqiansanzhangjieshao,zhuyaojiangleyixiemoxing,bingjinxingfenxi)

用matlab仿真实现了25 kHz 带宽内同时传送总共48 kbit/s 的两路语音(每路速率9. 6 kbit/s) 和两路数据信息(速率分别为19. 2 kbit/s 和9. 6 kbit/s) , 仿真结果表明达到了较好的误码性能。并比较了4 种数字调制方式下O FDM 系统的误码性能。(using Matlab Simulation bandwidth of 25 kHz simultaneous transmission within a total of 48 kbit/s 2 Road Voice (rate of 9 per road. 6 kbit/s) and two road data information (rate of 19. 2 kbit/s and 9. 6 kbit/s), the simulation results indicate achieve a better BER. And comparison of four types of digital modulation mode O FDM system BER.)

This program simultes the BER performance with a single and multiple users

通信仿真系统，通过搭建模型，运用此代码产生信噪比与误码率的关系图(Communication Simulation System)

小波分解与重构，单纯就是小波的分解和重构的m文件，没有其他多余没有用的文件，信号处理图像处理都很有用(Is simple wavelet decomposition and reconstruction of m documents, no other extra useless files, signal processing, image processing is very useful)
