WebApr 11, 2024 · Minimal codes are characterized by the property that none of the codewords is covered by some other linearly independent codeword. We first show that the use of a bent function g in the so-called direct sum of Boolean functions \(h(x,y)=f(x)+g(y)\), where f is arbitrary, induces minimal codes. This approach gives an infinite class of minimal codes … Webbinary Hamming code of order r. This is a [2r - 1, 2r - r-1] linear code with minimum distance 3. In the case r = 2, this is an MDS code, but it is a trivial one (a [3,1]-code).
