Webcalling Hamming code. A Hamming code is a combination of 0s and 1s, but not all combinations of 0s and 1s are valid codes. The Hamming distance between two binary numbers of the same length is the number of positions in the numbers that have different values. For example, the Hamming distance between 1101 and 1000 is 1, since they … WebPython 使用ECC生成至少在d hamming距离内的二进制字符串 ... # return sum(c1 != c2 for c1, c2 in zip(s1, s2)) # Wikipedia solution return np.count_nonzero(s1 != s2) # a faster solution def generate_hamm_arrays(n_values, size, min_hamming_dist=5): """ Generate a list of binary arrays ensuring minimal hamming distance between the ...
