The (7, 4) code given in Table 1 is a linear systematic block code; the rightmost four digits of each code word are identical to the corresponding information digits. A linear systematic (n, k) code is completely specified by a k x n matrix G of the ...
WebRepetition codes are the simplest type of linear block codes with error-correcting capability. A bit is encoded into a block of n identical bits, resulting in an (n, 1) block code. Assuming the code has error-correcting capability t, a bit is encoded as a sequence of 2 t + 1 identical bits, thus yielding 2 t + 1, 1 linear block codes.
