- A code C is said to be linear when it forms a vector space.
- That is, if C(m1) and C(m2) are codewords, then so are C(m1) + C(m2), and c x C(m1)
- Obviously, codewords are sparse in this n-dimensional space. (When n > k, C ? ?n )
- In fact, we should be able to represent any codeword as a linear combination of the basis vectors for that subspace C...
