Analysis of Absorbing Sets for Array-Based LDPC Codes
— Low density parity check codes (LDPC) are known to perform very well under iterative decoding. However, these codes also exhibit a change in the slope of the bit error rate (BE...

Decoding on Graphs: LDPC-Coded MISO Systems and Belief Propagation
— This paper proposes a new approach for decoding LDPC codes over MISO channels. Since in an nT × 1 MISO system with a modulation of alphabet size 2M, nT transmitted symbols are...
