Hamming Codes (2)
- A code word consists of 4 information bits and 3 check bits:
c = (i3 i2 i1 i0 c2 c1 c0)
- Each check bit covers:
c2: i3, i2, i1 c1: i3, i2, i0 c0: i3, i1, i0
- This relationship is specified by the generating matrix, G:
(1.26)
- Encoding of an information word i to produce a code word, c:
c = iG (1.27)
