最近在弄关于CDMA的东西，所以找了一些资料 ，也就把这个提供给大家共同分享(GOOD)

simulation modulate & demod FSK

说明：  用matlab开放环境实现了对数据的非线性回归，方便好用，直接将数据输入到程序中，便可以实现对数据的非线性回归(Open environment with matlab realize the non-linear regression of data, easy to use, enter data directly into the program, you can achieve non-linear regression of the data)

The book is divided into three parts: theory, method and implementation. Starting with a summary of the state-of-the-art in mobile technologies, the first part analyses their impacts on cartography and pinpoints the missing theories concerned with the development of map-based mobile services. A conceptual framework of mobile cartography is then introduced with the emphasis on mobile usage context. The second part is devoted to the design methodology under the constraints defined in the theoretical framework. A core issue deals with personalised mobile map services. The final part demonstrates the feasibility of the methods by using application scenarios.

用Simulink搭建的直接序列扩频（DS-SS）系统仿真模型，仿真结果比较理想。(A simulation on DS-Spread Spectrum communication system based on Simulink toolbox.)

使用最小二乘法平差，进行圆柱拟合，两次平差可以控制初始值尽量使结果收敛(application of TSL to fit for cylinder, control of start data to get a good result)

数字调制解调，包含数字调制程序和解调程序。(Digital modulation and demodulation, including digital modulation and demodulation process procedures.)

Matlab与HTK的接口程序，用于生成HTK中HMM的初始文件。(Matlab and HTK interface program used to generate the initial HMM file in HTK.)
