词条 | Minimum weight |
释义 |
In error-correcting coding, the minimum Hamming weight, commonly referred to as the minimum weight wmin of a code is the weight of the lowest-weight non-zero code word. The weight w of a code word is the number of 1s in the word. For example, the word 11001010 has a weight of 4. In a linear block code the minimum weight is also the minimum Hamming distance (dmin) and defines the error correction capability of the code. If wmin = n, then dmin = n and the code will correct up to dmin/2 errors.[1] References1. ^Stern & Mahmoud, Communications System Design, Prentice Hall, 2004, p 477ff. {{Telecomm-stub}} 1 : Coding theory |
