SPECTS_Summary
A serial concatenation scheme of LDPC (low density parity check) codes with a block interleaver is proposed and the performance is analyzed in this paper. Error performance of the proposed LDPC-LDPC code is compared with other codes under the same conditions. As results, The LDPC-LDPC code outperforms a single LDPC and turbo code. Moreover, it shows better performance than the LDPC-turbo code especially on a fading channel.
