对CA码进行bpsk调制后得到一个GPS中频信号，画出其时域和频域图

完整的qpsk通信系统，包括发送端，接收端，在不同的信道模型下的仿真：awgn，rayleigh。包括各种眼图，星座图，基带波形，载波波形。(Complete the qpsk communication system, including the sender, the receiver in a different channel model Simulation: awgn, and Rayleigh. Including a variety of eye diagram, constellation, waveform baseband carrier waveform.)

这是一个模拟枝晶生长的程序，能正常运行，实时更新图片(This is a program for simulating the growth of dendrites. It can run normally and update pictures in real time.)

Matlab里面没有提供直接以半径和圆心位置画圆的程序，该程序可以实现此功能，命令格式为：circle(radius,x0,y0, color )(Matlab which does not provide the location directly in the center circle radius and the program, the program can achieve this functionality, the command format is: circle (radius, x0, y0, color ))

在瑞丽衰落 =信道下，对信号进行qPSK调制(qpsk for relaygh channel)

动态3D心形图形的MATLAB源代码 有动态图形和MATLAB源代码(MATLAB source code of Dynamic heart shaped)

说明：  数字滤波器的代码，可用于运行仿真IIR与FIR类滤波器。(The code of the digital filter can be used to run simulation IIR and FIR type filters.)

这个文件是讲大规模MIMO的scm模型的。代码容易看看懂(this document descpbe)

说明：  尝试用粒子滤波(PF)进行GPS定位解算...........(Try to use particle filter (PF) for GPS Positioning Solution...)

simulation and software 的仿真代码第五章。 这是一本很好的通信系统仿真学习工具，国内几乎找不到原著。(simulation and software simulation code5. This is a very good learning tool for communication system simulation , domestic impossible to find the original . )
