Abstract
Recent promising theoretical results for repeat-accumulate (RA) codes, together with their extremely simple encoding, motivates this investigation into the design and implementation of practical RA codes. We consider two main issues: the construction of the interleaver in fixed length codes using combinatorial designs; and the improvement of the error floor performance of RA codes by modifying the accumulator
