Binary linear code
WebApr 13, 2024 · Suppose C denotes a linear binary code. Partition C into two subsets C 0 and C 1 consisting respectively of all the codewords of even Hamming weight and all the codewords of odd Hamming weight. Show that for every linear binary code, C 0 is a non-empty set. Hint: find a codeword of even weight in C. (Subhint: 0 is an even integer). 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 …
