Option 3 : Hamming code

Hamming code:

Hamming codes are linear block codes. The family of (n, k) hamming codes for q ≥ 3 is defined by the following expressions:

1. Number of Block diagrams (n) = 2q – 1

2. Number of message bits (k) = 2q – q – 1

3. Number of Parity bits (q) = (n – k)

Hamming code is a set of error-correction codes that can be used to detect and correct '1' bit errors that can occur when the bitstream is sent through the channel. It can be employed in both burst and signal error correction.

Which of the following codes uses a number of parity bits located at certain positions in the codeword and uses the relations between redundancy bits and the data bits?
