Abstract :
This paper presents a possible interconnection structure suitable for being used in a flexible LDPC decoder. The main feature of the proposed approach is the possibility of implementing parallel or semi-parallel decoders with a reduced communication complexity. To the best of our knowledge this is the first work detailing the implementation of a fully flexible LDPC decoder, able to support any type of code. To prove the effectiveness of this approach, a complete decoder has been implemented on a XC2V8000, achieving a decoding throughput of 529 Mbps on a (1920, 640) code
