Hamming error-correcting code (ECC) is a method of both detecting and correcting errors in data. It can be used for storage and transmission integrity. Error correcting codes work by mathematically combining data values, such that if the math isn’t equal when you look at it later, something...
A Robust Audio Authentication Scheme Using (11,7) Hamming Error Correcting CodeIn the advancement of high-speed internet technology and vast use of social media, people are sending audio and video message for their daily communication in case of textual information. Due to unprotected nature of ...
汉明码是Richard Hamming于1950年提出的。是目前广泛采用的一种有效的校验码，其中，主存的ECC(Error Correcting Code)采用的就是类似的校验码。---摘自百度百科 这个分组的思想有点不是很理解。以下使用P代表校验位，H代表汉明码，D代表原始信息位，N位信息位的位数，K位校验位的位数。 则N与...

In telecommunication, Hamming codes are a family of linear error-correcting codes that generalize the Hamming(7,4)-code, and were invented by Richard Hamming in 1950. Hamming codes can detect up to two-bit errors or correct one-bit errors without detection of uncorrected errors. By contrast, ...

经过深入探讨,1947年哈明终于发明了一种能纠错的编码,这种码就叫“纠错码”(error-correcting-code)或“哈明码”(Hamming code)。哈明码是一种冗余码,即在有效信息代码中要加入校验位,这是为纠错而必须付出的代价。其基本原理是使每一信息位参与多个不同的奇偶校验(parity check)。所谓奇偶校验是在代码中设置一个...
You need to get into a new field to get new viewpoints, and before you use up all the old ones. You can do something about this, but it takes effort and energy. It takes courage to say, ``Yes, I will give up my great reputation.'' For example, when error correcting codes were ...
