WebThe Hamming distance between two codewords is defined as the number of elements in which they differ. The minimum distance dmin of a linear block code is the smallest Hamming distance between any two different codewords, and is equal to the minimum Hamming weight of the non-zero codewords in the code. Example 10.4. WebAs satellite observation technology rapidly develops, the number of remote sensing (RS) images dramatically increases, and this leads RS image retrieval tasks to be more …
