Textbooks

Lin and Costello: Error Control Coding 

For a concise introduction, I highly recommend the book: Error Control Coding by Peter Sweeney. Wiley, 2002.

Simon Haykin, Digital Communications, Wiley; For general digital communication theory

R. Gallager, Reliable Communications for basic introduction to Information Theory
