This book is an introduction to information and coding theory at the graduate or advanced undergraduate level. The function hamming_distance(), implemented in Python 2.3+, computes the Hamming distance between two strings (or other iterable objects) of equal length by creating a sequence of Boolean values indicating mismatches and matches between corresponding positions in the two inputs and then summing the sequence with False and True values being interpreted as zero and one. In the Hamming code, k parity bits are added to an n-bit data word, forming a new word of n k bits. This can be reported, but it can't necessarily be corrected, since the received code may differ in exactly two bits from several of the codes in the table. Author: fish. The simplest of the error-correcting codes is the Hamming code devised by Richard Hamming at Bell Laboratories. Data + Parity = 000111000011, In the above example we have taken data as “01100011” and final transmitted data by adding parity bits is “000111000011”.
