marmousi模型双线性插值

Sharpness detection algorithm.

In cryptography, SHA-1 is a cryptographic hash function designed by the United States National Security Agency and published by the United States NIST as a U.S. Federal Information Processing Standard. SHA stands for "secure hash algorithm".

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)

拟合zernike多项式,这里给出了前35项的泽尼克像差。有需要的话可以继续添加像差。(Fitting zernike polynomial.The zernike aberrations of the first 35 terms are given here. Continue to add aberrations if necessary)

基本的源程序，可用于日常对matlab的学习与应用当中。(Basic source, can be used for day-to-day of the study and application of matlab them.)

说明：  协作通信三种协作方式（AF DF CC）的matlab仿真程序，可以得到误码率的比较(Collaboration collaborative communication in three ways (AF DF CC) of matlab simulation program can be obtained BER Comparison)

BPSK平坦瑞利信道下的最大信噪比合并仿真的matlab程序，希望大家下载(BPSK Rayleigh flat channel with the greatest signal-to-noise ratio of Matlab simulation procedures in the hope that you download)

有关时间序列的计算，分析，结果输出的matlab原代码(For the calculation of time-series analysis, the results of the output matlab source code)

压缩感知中基于m序列的测量矩阵的构成，代码在matlab上进行了仿真，效果好于传统高斯矩阵。代码有详细注释，易懂(This codes described measurement matrix based on m sequences in Compressed sensing. It has good result in matlab environment and the effect is better than the traditional Gaussian matrix. Code has detailed notes, so ti is easy to understand.)
