I'm not sure if this is what you are looking for - the best book on signal coding [in particular designing & testing coding schemes] I've come across is "The Theory of Error-Correcting Codes - F.J. Macwilliams, N.J.A Sloane."

Dear Ndolo A.O.,

Best book and research article with signal coding & estimation especially in Powerline Communications.

I hope the information will help you.

With Best Wishes,

Samir G. Pandya

Thanks a lot Dr. Samir.
