This paper introduces a novel Serial Code Concatenation (SCC) scheme to combat the error floor problem experienced in iterated sparse graph-based error correcting codes such as Turbo Product (TP) codes and Low Density Parity Check (LDPC) codes. SCC has been widely used in the past to reduce the error floor in iterative decoders. However, the main stumbling block for its practical application in high speed communication systems has been the need for long and complex outer codes. The use of short outer block codes with interleaving has been shown to provide a good tradeoff between complexity and performance.
