 X, Y coordinates points for the graph is generated randomly and put it in a trace file. The trace file is given as input file to xgraph to plot the graph. Here two trace files are plotted in the single graph. Point of each trace file will be differentiated in color.

引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．-The introduction of PEG (Progressive-edge-growth) algorithm to construct suitable for linear time encoding of LDPC check matrix, decoding simplified when the smallest and the Min-Sum decoding algorithm decoding simplified. Simulation results show that this method can construct LDPC codes suitable for linear time encoding on lower triangular calibration matrix, and constructed using this method the performance of LDPC code is very close to the original PEG algorithm constructed LDPC codes. At the same time through the use of the smallest and the Min-Sum decoding algorithm to reduce complexity.

本文讲述了linux操作系统下网络编程的相关步骤。 　Linux的源码里，网络接口的实现部份是非常值得一读的，通过读源码，不仅对网络协议会有更深的了解，也有助于在网络编程的时候，对应用函数有更精确的了解和把握。 　　本文把重点放在网络接口程序的总体结构上，希望能作为读源码时一些指导性的文字。 -This article describes network programming under linux operating system of the relevant steps. Linux source code, the network interface to achieve most of it is very worth reading, by reading the source, not only on the network will have a deeper understanding of the agreement, will also help in network programming when the application has a more precise function understanding and grasp. This article focused on the network interface on the overall structure of the procedure, hoping for some guidance when reading source code of the text.
