实现无线电导航的原理，基于三边测量定位对导航和GPS（全球定位系统）的实现。同时实现了，GPS广播星历参数算法，电离层误差、对流层误差、卫星等仿真(Implement the principle of radio navigation, positioning for navigation based on trilateration and GPS (Global Positioning System) implementation. While achieving, GPS broadcast ephemeris parameter algorithm, the ionosphere error, troposphere error, satellite and other simulation)

维特比译码matlab仿真 详细过程有注释，方便学习使用，挺好用的，望保留实用(Viterbi decoding matlab simulation detailed process notes, facilitate learning to use, very easy to use, hope to retain the practical)

该资料是我当时在学MATLAB时使用的资料，很好用的。(MATLAB)

说明：  构造限制三体问题中平动点周围的halo轨道，实现对太空环境定点观察(Restricted three-body problem Zhongping construct fixed points around the halo orbit, the space environment to achieve the fixed observation)

GMRES算法，求解大型稀疏线性方程的快速数值解法，方便实时求解(GMRES algorithm is prosed to solve Large- scale sparse linear equations)

CDMAT-ransmitter receiver-CDMA is an access technique which uses entire for communication

说明：  MATLAB边值问题求解的文档和源代码，好东西啊，强烈推举爱女(MATLAB to solve boundary value problems for the documentation and source code, good things ah, strongly favored daughter elected)

说明：  利用压缩包内的5和函数产生PPM调制的UWB信号，信号波形为高斯二阶导函数。重复编码次数，TH码长度范围，波形形成参数alpha等参数均可以改变(use compressed within the five functions to generate PPM and the UWB signal modulation, Waveform second derivative of the Gaussian function. Repeat code number, TH code length, alpha waveform parameters such as formation parameters can be changed)
