Turbo 码作为一种性能优越的信道码, 其应用逐步推广到深空通信、卫星通信和移动通信, 并被推荐为第三代移动通信的信道编码方案之一。本设计实现了通用的Turbo 码的编译码(Turbo codes as a superior performance of channel code, its application gradually extended to deep space communications, satellite communications and mobile communications, and was recommended as one of the channel coding scheme third generation mobile communications. The design and implementation of the encoding and decoding of Turbo codes common)

This derivation of the normalised least mean square algorithm is based on Farhang- Boroujeny 1999, pp.172-175, and Diniz 1997, pp 150-3. To derive the NLMS algorithm we consider the standard LMS recursion, for which we select a variable step size parameter, μ(n). This parameter is selected so that the error value , e+(n), will be

解决大规模限量弧路由的程序，本程序采用了PAM聚类的方法。(To solve large-scale limited arc routing procedures, the program uses a PAM clustering method.)

说明：  声明：本程序仅交流用，所以调试时用两颗棋子就可以赢(Disclaimer: This procedure only exchange with, so debugging can win with two pieces)

说明：  声波方程正演模拟大模型样例。 包含三个地质层，分别对应速度可以自行修正。 震源函数是雷克子波。 C源程序，输出结果Matlab绘制。(Acoustic wave equation forward modeling big model of the sample. Consists of three geological layers, corresponding to the speed you can correct itself. Lake wavelet source function is. C source code, the output of Matlab draw.)

通过M atlab 模拟了随机产生的一定概率分布的信号序列, 叠加高斯噪声后利用最大后验概率(MAP)检 测到的误码率, 做出BER~ SNR曲线, 并与理论计算得到的曲线进行比较, 两者吻合.(M atlab simulated by a certain probability distribution of random signal sequence, use of superposition of Gaussian noise is the maximum a posteriori (MAP) detection to the error rate, making BER ~ SNR curves obtained with the theoretical curve of the combined fit.)

一个二维的fdtdc++编写的程序，较完整，带有pml边界条件。感兴趣的可以下载看看。(A two-dimensional fdtdc++ preparation procedures, more complete, with pml boundary conditions. Interested can download to see.)
