What is a perfect code?

Perfect codes

Codes that attain the Hamming bound are called perfect codes. Examples include codes that have only one codeword, and codes that are the whole of. . Another example is given by the repeat codes, where each symbol of the message is repeated an odd fixed number of times to obtain a codeword where q = 2.

Is Hamming code a perfect code?

Hamming codes are perfect codes, that is, they achieve the highest possible rate for codes with their block length and minimum distance of three. Richard W. Hamming invented Hamming codes in 1950 as a way of automatically correcting errors introduced by punched card readers.

What is Hamming code with example?

The amount of parity data added to Hamming code is given by the formula 2^p ≥ d + p + 1, where p is the number of parity bits and d is the number of data bits. For example, if you wanted to transmit 7 data bits, the formula would be 2⁴ ≥ 7 + 4 + 1, so 4 parity bits are required.

Which of the following is an example of perfect code?

Hamming codes and the Golay code are the only nontrivial examples of perfect codes.
