gsm 规范。对学习电信的人很有帮助 。-gsm norms. On learning of telecommunications helpful.

用MSComm进行串口编程，已在Delphi6.0环境下编译通过-MSComm carried out using serial programming environment has been compiled through Delphi6.0

This paper characterizes the multicell precoding game where block-diagonalization (BD)-based precoding is utilized on a per-cell basis for downlink transmissions.

这是一个使用modem拨号上网的程序，可以使用，在gprs方式下也可使用，是用gprs通信的很好的例子程序-It is a modem dial-up procedures can be used in GPRS mode also can be used. GPRS communication is a good example of procedures

这片是写的数据信号处理可查那个设计的报告，报告包括卷积演示程序、演示采样定理、模拟滤波器设计演示―从模拟低通滤波器到模拟高通、带通、带阻的幅度 特性对比演示、切比雪夫I型低通滤波器、利用凯塞窗设计高通滤波器、使用双线性变换法设计巴特沃斯低通数字滤波器 这几个部分..........用matlab实现 -this piece is written data signal processing design can be found that the report, including the convolution Demonstration Program, Presentations sampling theorem, Analog Filter Design demo-from analog low-pass filter to simulate high-pass, band-pass, with the rate of resistance properties compared demo, I Chebyshev low-pass filter, the use of Kaiser window design high-pass filter, use bilinear transform design Butterworth low-pass digital filter these parts .......... used mat Implementation lab

一种快速的圆检测方法,可以检测圆。。效果还可以-A Fast circle detection method can detect the circle. . Effects can also be

空间谱估计算法，是研究信号噪声比的。效果还可以-Spatial spectrum estimation algorithm, is to study the signal-noise ratio. Effects can also be

采用VS2010平台实现了FFT变换，其中采用原位运算方式，精度为浮点（运算量和精度的折中）。利用指针传递参数，输入和输出为同一数组，包含实部和虚部。画图部分用于显示运算结果。从图像显示的计算结果来看，FFT运算结果正确。
