VC++编码实现的（7，4）海明码，程序运行正确，用VC实验得到在硬软判决下的误码率。再用Matlab讲得到的数据进行绘图。-The realization of (7,4)hamming coding under the VC++.The program runs corectly,resulting the BER under several types.Finally, use the matlab to map with datas.

this program for detecting the 1 bit errors in the given message and correcting them by using check bits by the hamming code method.

汉明码源码，采用74汉明码编码，实现3位可纠错编码(Hamming code source code, using 74 Hamming code, to achieve 3 bit error correction coding.)
