说明：  网格码，主要是进行TCM码编制。希望对大家有用。(Grid code, mainly for the preparation of TCM codes. Hope to be useful.)

说明：  长期演进系统，通信链路自动重传情况解析。获取是否自动重传(Long-term evolution system, automatic retransmission of communication links)

说明：  由于时域求导有误差，用来在频域处理时域信号数据。(It is used to process time domain data in frequency domain.)

说明：  bpsk分布，awgn,瑞丽衰落信道，调制解调加滤波，计算误码率(BPSK distribution, awgn, Ruili fading channel, modulation and demodulation increase filtering, bit error rate calculation)

这个是关于matlab的，里面有matlab的大量可供参考的案例，还有几个ppt也是这方面的，比较好，分享给大家。(This is mainly the MATLAB language and control system simulation, there are a large number matlab reference case, there are a few ppt is in this respect, better, to others.)

有限元法三角形单元单元分析，有限元初学者编写，进行电算验算(The finite element method of triangular element unit analysis, finite element beginners, checking the superhighway )

说明：  目前各类粒子群算法的应用、改进、参数设置方法(At present the application of various types of particle swarm optimization, improvement, parameter setting method)

对stoke 方程的非协调员的新型解法,效率高，求解时间段等特点(a new method for stoke equation)

本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性，缩短多普勒频移的 捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式，然后根据数值分析结果得到了准最佳捕获判决策略，最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高. (This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)
