说明：  这是一个通信系统，复用资源下协作方案性能仿真(This is a communication system, the performance simulation of cooperation scheme under reuse resources)

GMSK调制解调 能运行 绝对好用 包括原理 注释全(GMSK modulation)

说明：  cclink -ie 通讯手册 ，需要的朋友可以看一看(cclink -ie Communication manual)

说明：  conversion of a matrix into lower triangular matrix

数组可以存放5个人的姓名，每个姓名包括first name，middle name和last name，输出姓名时，其中middle name只取大写的首字母，利用索引编写程序，使得用户输入last name后，输出姓名的全称。(array can store the names of five individuals, including the names of each first name, middle name and last name, the name of the output, which only middle name from the first uppercase letter, the use of indexing programming, enabling users to import last name, the name of the generic output.)

uwb仿真，上传到上来给大家一个参考，希望能有帮助(UWB simulation, upload onto a reference to the U.S., hoping to have help)

说明：  设计一个巴特沃兹数字低通滤波器，其技术指标为：3dB带宽为0.2π，阻带截止频率为0.3π，通带纹波为1dB，阻带衰减大于30dB，采样间隔T=10ms。 1）采用冲激响应不变法； 2）采用双线性变换法设计； 3）采用FIR的窗函数（Hanning窗、Hamming窗或Blackman窗）设计。(A Butterworth digital low-pass filter is designed. Its technical specifications are: 3 dB bandwidth is 0.2 pi, stopband cut-off frequency is 0.3 pi, passband ripple is 1 dB, stopband attenuation is more than 30 dB, sampling interval T=10 Ms. 1) Impulse response invariance method is adopted. 2) Design by bilinear transformation method; 3) FIR window function (Hanning window, Hamming window or Blackman window) is used to design.)
