说明：  基于多卫星的GPS中频信号生成方法，通过分析单卫星信号的模拟搭建，改进为多卫星的实现方法。(Based on the multi-satellite s GPS intermediate frequency signal production method, through analyzes the single satellite signal the simulation build, improves realizes the method for the multi-satellites.)

1、设计一个62阶低通滤波器，采样频率为9kHz，通带截止频率为3kHz，要求阻带最小衰减50dB。 2、将滤波器系数输出到txt文本文档。 (1, the design of a 62-order low-pass filter, the sampling frequency is 9kHz, passband cutoff frequency of 3kHz, requires a minimum stopband attenuation 50dB. 2, the output of the filter coefficients to txt documents.)

计算隐马尔可夫模型序列的最可能的状态路径(Hidden Markov model to calculate the most likely state sequence path)

动态时间规整matlb源码，相比于欧式距离更能体现相关性(Dynamic time warping matlb source, compared to the Euclidean distance to better reflect the relevance)

说明：  卡尔曼滤波器，可以对所得到的数据进行平滑，matlab源码(Kalman filter can be obtained by smoothing the data, matlab source)

Effect of Frequency offset on OFDM

联盟博弈频谱感知，包括融合和分裂算法，本科毕设时用的，看下面的英文文献，是对应的文章中仿真的哈，推荐(coalitional games for distributed collaborative spectrum sensing in cognitive radio network)

Determinant of the permutation matrix with rows ordered by p.

此程序是matlab中有关平滑去噪中常用的散射校正的程序，简单使用，其中的注释详细，对每个变量的注释都很清楚(This procedure is related to smoothing denoising matlab commonly used scatter correction procedures, simple to use, with detailed explanatory notes for each variable are well aware of the Notes)

差分格式编码，用matlab仿真，结果可以仿出来，有需要的就下吧(Differential encoding format, with the matlab simulation, results can fake it, need it for the next)
