QPSK_Modulation

蒙特卡洛(Monte Carlo)方法，是一种基于计算机“随机数”的计算方法。(Monte Carlo (Monte Carlo) method, is a computer-based " random" is calculated.)

与已有的代码相比，本代码不仅包含调制解调、星座图、误码率等已有功能，更添加蒙特卡洛仿真，具有更好的性能，程序会产生一些图，能看清楚调制解调的过程中一步一步的编解码过程。(Compared with the existing code, the code contains not only the modulation and demodulation, constellation diagram, such as bit error rate for existing function, more add a Monte Carlo simulation, has better performance, the program will produce some map, can see the encoding and decoding process step by step in the process of modulation and demodulation..)

对给定的正方矩阵进行Doolittle分解，并分析其计算量。(Doolittle given matrix decomposition)

很好的实现了LDPC码字的生成，强烈建议使用此生成矩阵进行编码调制(LDPC codeword generated, it is strongly recommended to use this generator matrix code modulation)

source code for split and merge of image

Using Matlab, 很好很基础的书(Using Matlab, good and basic introduction)

[WuYuFei]中是WuYuFei的论文 [WuYufei_matlab]是WuYufei的Matlab程序 做Turbo码，恐怕很难绕过WuYufei的程序，呵呵 [cap_turbo]和[mother]是我在研究阶段的工作 走了很多弯路，所以这两个目录必然有很多错误而且很混乱 如果想了解一下我的研究历程可以看看，切不可拿来修炼，否则走火入魔俺不管。平，mdsvl,sdlxcl([WuYuFei] is WuYuFei papers [WuYufei_matlab] is a Matlab program to do WuYufei Turbo codes, it would be difficult to bypass WuYufei procedures, Oh [cap_turbo] and [mother] at the research stage of my work take a lot of detours, so These two directories must have a lot of mistakes and a lot of confusion if you want to know can see my research process, must not be used practice, or whether I possessed by the Devil.)

PN码发生器的matlab程序，对于写vhdl代码有很重要得参考价值(PN code generator matlab procedures, write VHDL code for a very important reference value was)

说明：  对输入的信号计算其的分形维数，用以判断信号的复杂度(The input signal to calculate the fractal dimension of complexity to determine the signal)
