零基础学Visual C++的课件，可以帮助读者快速提高Visual C++编程能力(Zero-based Visual C++ courseware, fast to improve Visual C++ programming ability can help readers)

说明：  实现了一个直接扩频系统，使用BPSK作为调制解调方法。并比较白噪声AWGN及瑞利衰落(rayleigh fading)环境下，误码率的影响。(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray >>semilogy([1:8],BER_awgn(1:8), g* ) hold on semilogy([1:8],BER_ray(1:8), -.b* ) hold on grid on )

说明：  c语言程序教你快速学习模仿程序，很快进入语言环境(c language program to teach you quickly learn to imitate procedures, and soon enter the language environment)

用于基站定位的RSA算法，采用sdp工具箱求解二次规划问题，增加紧约束条件得到更加精确的MS位置。(The RSA algorithm for base station location uses the SDP toolbox to solve the quadratic programming problem, increasing the tight constraints and obtaining a more precise MS location.)

说明：  在瑞利信道中，对于OFDM信号设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线(In Rayleigh channel, a specific guidance aided channel estimation method is designed for OFDM signal, and the simulation is carried out with Simulink to measure the BER performance of BPSK modulation. The relation curve between bit SNR and channel estimation mean square error is drawn, and the relation curve between bit SNR and bit error rate is drawn)

PID是控制中最为常用的算法，本程序包提供了PID参数设计模型，同时也提供了相应的具体实例。(PID is the most popular algorithm in control system, this package provides the modelling for PID parameter optimizing and the examples are presented as well.)

VB编写的一个有限元计算的例子，内容比较全面，包含网格划分，梁，桁架，热传输等情况的计算，以及后处理的显示。(An example of a finite element calculation written in VB, it is more comprehensive, including meshing, calculation beams, trusses, heat transfer, etc.as well as display after treatment.)
