GPS-signal--BPSk-modulation

主要包含Zigbee的物理层仿真源码，实现Zigbee的物理层协议(a matlab source for Zigbee)

一个完整的ofdm调制系统的仿真程序，包含PN码自动生成，串并转换等各功能模块和算法，重点针对不同信道条件对常用及各种信道盲均衡算法进行仿真分析比较，对不同原型滤波器算法进行研究分析，分析比较QAM系统，供博士毕业论文参考(Ofdm modulation of a complete system simulation program, including automatically generated PN code, and convert the string Other functional modules and algorithms, focusing on a different channel conditions and a variety of common blind channels are Balance simulation algorithm analysis and comparison of different research and analysis prototype filter algorithm, sub- Analysis of more QAM systems, Ph.D. thesis for reference)

说明：  oust图像分割，最大类间方差，多阈值图像分割(Oust image segmentation, maximum inter-class variance, multi-threshold image segmentation)

这是一份低轨道卫星建模的资料，比较简洁适合学习(This is a low-orbit satellite modelling data, relatively simple and suitable for learning, recommend to see)

random and queuing theory(mm1)

基于频谱细化的线性调频信号的参数估计。首先对中频信号延时相乘然后对产生的序列做FFT，初步算出LFM信号的调频斜率，然后用CHIRP-Z变换精确估计。(Estimated based on the parameters of the linear FM signal spectrum refinement. First of delay multiplied by the IF signal and then do the FFT on the resulting sequence, initially calculated the slope of the LFM signal FM accurate estimate, and then use the CHIRP-Z transform.)
