Accelerating LDPC decoding using multiple-cycle eigenmessages

Abstract

The eigenmessage decoder O. Chauhan et al. (2003) expresses a degree of nonlocality in a message passing decoder by representing an entire cycle in a single linear equation. The eigenvector for the linear message passing matrix represents a fixed point of the message passing algorithm around a cycle and has been shown to significantly decrease the number of… (More)
