  • Hard-decision decoding scheme Codeword length (n) : 31 symbols. Message length (k) : 19 symbols.

    Hard-decision decoding scheme Codeword length (n) : 31 symbols. Message length (k) : 19 symbols. Error correction capability (t) : 6 symbols One symbol represents 5 bit. Uses GF(2^5) with primitive polynomial p(x) = X^5 X^2 + 1 Generator polynomial, g(x) = a^15 a^21*X + a^6*X^2 + a^15*X^3 + a^25*X^4 + a^17*X^5 + a^18*X^6 + a^30*X^7 + a^20*X^8 + a^23*X^9 + a^27*X^10 + a^24*X^11 + X^12. Note: a = alpha, primitive element in GF(2^5) and a^i is root of g(x) for i = 19, 20, ..., 30. Uses Verilog description with synthesizable RTL modelling. Consists of 5 main blocks: SC (Syndrome Computation), KES (Key Equation Solver), CSEE (Chien Search and Error Evaluator), Controller and FIFO Register.

  • 基于"trace transform"的识别2D图像的C++源程序

    基于"trace transform"的识别2D图像的C++源程序, 主文件是tt.cpp, 在LINUX下可以用 g++ tt.cpp -o tt -O3进行编绎, 而且最后的结果也可以在MATLAB下显示出来, This package presents C++ tools to the trace transform of a 2D image, and related objects, i.e. circuses and triple features, matlab tools to visualise these entities, and tools to check newly coded functionals. This version is released with a small number of functionals only.

  • 用PHP编写的表达式计算器

    用PHP编写的表达式计算器,是用的编译的知识实现的,并非使用eval()函数实现。 功能强大,可以做所有的数值计算,代数计算还不能实现。 1。可以计算形如“-3*sin(2^0.5/2+3.1415)-pi()^2”的式子。 2。能识别数字(包括小数、正负数)、数学函数。 3。可以做加、减、乘、除、指数、取模 计算(其中加、减包括一元和二元两种操作)。 压缩包里的“math.php”是演示文件

  • 考察例1 4 - 8中的1 4个点。A中的最近点对为(b,h)

    考察例1 4 - 8中的1 4个点。A中的最近点对为(b,h),其距离约为0 . 3 1 6。B中最近点对为 (f, j),其距离为0 . 3,因此= 0 . 3。当考察 是否存在第三类点时,除d, g, i, l, m 以外 的点均被淘汰,因为它们距分割线x= 1的 距离≥ 。RA ={d, i, m},RB= {g, l},由 于d 和m 的比较区中没有点,只需考察i 即可。i 的比较区中仅含点l。计算i 和l 的距离,发现它小于,因此(i, l) 是最近

  • 利用函数MadHG生成规则LDPC码的校验矩阵H

    利用函数MadHG生成规则LDPC码的校验矩阵H,其行重为6,列重为3,行数为列数一半(行数越大越好),H中任意两列没有围长为4的圈,并得到H对应的生成矩阵G,可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),

  • penMesh is a generic and efficient data structure for representing and manipulating polygonal meshes

    penMesh is a generic and efficient data structure for representing and manipulating polygonal meshes. OpenMesh is developed at the Computer Graphics Group, RWTH Aachen , as part of the OpenSGPlus project, is funded by the German Ministry for Research and Education ( BMBF), and will serve as geometry kernel upon which the so-called high level primitives (e.g. subdivision surfaces or progressive meshes) of OpenSGPlus are built. It was designed with the following goals in mind : Flexibility : provide a basis for many different algorithms without the need for adaptation. Efficiency : maximize time efficiency while keeping memory usage as low as possible. Ease of use : wrap complex internal structure in an easy-to-use interface.
