Abstract :
This paper presents a new scheme of serially concatenated codes. It is formed by a combination of Euclidean Geometry (EG) Low Density Parity Check (LDPC) and Recursive Systematic Convolutional (RSC) codes linked by the row-column interleaver. A modification is proposed on the interleaver, which improves performance of concatenated codes. This is conducted by recognition of patterns producing low-weights for both LDPC and RSC codes. Simulation results confirm that with similar rates and less decoding complexity, newly designed codes outperform product codes constituted by two cyclic EG codes.
