I'm having trouble with a question on degenerate cyclic codes. I'm not sure if anybody can help me but the question is Q22 page 224 chapter 8 in Macwilliams and Sloane's 'The Theory of Error-Correcting Codes.' I can type the question out if you don't have the book.
Thanks
The particular question is --
Let C be a linear code with no coordinate position always zero, in which there is only one nonzero weight. Show that there is a minimal ideal M of F[x]/<x^n - 1> such that C is equivalent to the code {|u|u| ... |u|: u in M}
Cheers
