Assignment:
A (n, k) Hamming code C can be expanded by appending one parity symbol at the end of each codeword so that it has even Hamming weight. Write the rule to determine cn+1 from c1,...,cn.
a) Show that the expanded (n + 1, k) code C is linear.
b) Write generating and parity-check matrices for C starting from C being the (7, 4) Hamming code.
c) Find the minimum distance of C How many errors can C detect?
