A-REMARK-ON-COMPRESSED-SENSING
说明： 一篇关于压缩感知的经典文章，压缩感知（Compressed sensing，简称CS，也称为Compressive sampling)理论异于近代奈奎斯特采样定理，它指出：利用随机观测矩阵可以把一个稀疏或可压缩的高维信号投影到低维空间上，然后再利用这些少量的投影通过解一个优化问题就可以以高概率重构原始稀疏信号，并且证明了这样的随机投影包含了原始稀疏信号的足够信息。(A classic article on compressed sensing, compressive sensing (Compressed sensing, referred to as CS, also known as Compressive sampling) different from the modern theory of the Nyquist sampling theorem, which states: the use of a random measurement matrix can be sparse or compressible high-dimensional signal projected to low dimensional space, and then use a small amount of projection by solving an optimization problem to be sparse with high probability to reconstruct the original signal, and prove that random projection of the original sparse signal contains enough information.)

这里给出的源代码huffman.zip用8种不同的方式实现了Huffman编码算法。这些代码意在演示不同Huffman算法的实现原理，比较算法执行效率的差别，但并没有针对实际应用环境的需求，做更多的空空空间或效率优化。全部代码以C++语言开发，为了更容易地实现各种数据结构，代码中大量应用了标准C++库与模板技术。——总之，这些代码的作用在于示例与演示；如果大家想把这些代码应用在实际应用中，可能还需要
(The given here source code huffman.zip eight different ways to achieve the Huffman coding algorithm. These codes are intended to demonstrate different Huffman algorithm implementation principle, the difference of the algorithm execution efficiency, but does not demand for practical application environment, do more empty space or efficiency optimization. The entire code C++ language development code in order to make it easier to achieve a variety of data structures, a large number of applications the standard C++ library template.- In short, these code examples and demonstration If we want the code used in practical applications may also need)

FDR-COMPRESS
一种改进的方案，它针对硬故障集的特点利用指示频率连续长度码(FDR码)进行二次编码压缩。该方法充分利用测试集中无关位较多而测试模式之间变化位较少的特征，应用贪心算法对预先计算的测试集进行了重新排序，尽可能的使相邻的向量间具有最少的不同位，排列成一个最佳的差分向量序列，然后应用FDR码对差分向量序列进行编码,最后对压缩结果重新分块，按照一次压缩的流程进行二次压缩。在解压时，使用片上解压电路解压，能高效地还原出原测试集。最后通过对Soc部分标准电路硬故障集的测试结果显示，本方案具有较好的压缩率。(a new improved method was proposed in the paper,the method using Frequency-Directed Run-length(FDR codes)coding for the twice aimed at hard-fault. It fully takes advantage of the characters that there are many don’t-care bits in the test set but a few different bits between the test patterns, Then it applies the greed calculate way to sort the precomputed test sets and make the close together vector have the least different sites possibly. It uses the FDR codes to coding the vectors,then blocks the results and uses the FDR codes to compress for the second time.
Decompression used of on-chip circuit extract unpack,it will be deoxidize the original test efficient.using the hard-fault to compress and the experimental results prove that the improved coding method of this paper has the better compression ratios has been proved at last.
