Abstract

AccumulateRepeat-4 Jagged-Accumulate (AR4JA) codes, which are channel codes designed for deep-space communications, are a series of QC-LDPC codes. Structures of these codes' generator matrix can be exploited to design reconfigurable encoders. To make the decoder reconfigurable and achieve shorter convergence time, turbo-like decoding message passing (TDMP) is chosen as the hardware decoder's decoding schedule and normalized min-sum algorithm (NMSA) is used as decoding algorithm to reduce hardware complexity. In this paper, we propose a reconfigurable decoder and present its FPGA implementation results. The decoder can achieve throughput greater than 74 Mbps.
