WebUsing the equation ci= (dot product of u and vi)/ vi ^2 we can obtain scalars for c where u=c1*v1+c2*v2+c3*v3 Again how can you find this vector u using the linear combination of the vectors in S if S is linearly independent? There should not be a vector u that is a linear combination of the vectors in S if S is linearly independent. WebLinear Codes In general, finding the minimum distance of a code requires comparing every pair of distinct elements. For a linear code however this is not necessary. Proposition 4: In a linear code the minimum distance is equal to the minimal weight among all non-zero code words. Proof: Let x and y be code words in the code C, then x - y is in C
