matlab环境下的GPS信号捕获仿真 GPSAquisition

说明：  matlab与stk的联合仿真的二次开发，这写的是四颗卫星访问地面站的例子，有兴趣可以来看一看，我们一起研究。(The second development of the joint simulation of MATLAB and stk, which is an example of four satellites visiting ground stations, is interesting to see, we will study together.)

The following file contains three types of digital communications sampling. Contains ideal sampling, natural sampling and ZOH sampling, operate only for one single frequency signal, can be modified to add multiple signals with a base frequency. Greetings, I hope it helps.

说明：  亲测好用的基本的自适应波束形成，LMS和RLS，可以在此基础上改进(Adaptive beamforming, LMS and RLS)

结合QPSK调制的直接序列扩频系统的仿真(Combined with QPSK modulation direct-sequence spread-spectrum system simulation)

MATLAB GUI实现串口程序（原创）(MATLAB GUI Serial program(original))

说明：  进行FDOA频差定位的程序，计算GDOP(Carry out FDOA frequency difference positioning program and calculate GDOP)

OFDM系统包括OFDM系统的调制解调，IFFT及FFT变换，保护间隔的加入对系统性能的改善，以及多径干扰、高速移动对系统误码率的影响。(The OFDM system includes modulation and demodulation of the OFDM system, IFFT and FFT transformation, the improvement of the protection interval to the system performance, and the influence of multipath interference and high-speed mobile on the system BER.)

一个人工免疫的多目标程序，可以绘制相应的pareto前沿(A multi-objective program of artificial immune system can draw corresponding Pareto frontiers)

运通GPS第二版 服务器源代码，完整版 结构清晰(yun tong gps SERVER 2ND)

说明：  基于接收信号强度的KNN室内定位算法，还有测试数据。适合初学者参考(KNN indoor positioning algorithm based on the received signal strength, as well as test data. For beginners)
