A satellite receiver comprises a front-end, demodulator and an LDPC decoder. The front-end receives a DVB-S2 LDPC coded signal and provides a down-converted signal to the demodulator. The latter demodulates the down-converted signal and provides a demodulated signal to the LDPC decoder. The LDPC decoder has a partially parallel architecture and partitions the bit node messages into N/360 groups and the check node messages into q groups, where q=M/360. Each group is processed by 360 bit node processors or 360 check node processors, respectively. Illustratively, the LDPC decoder includes a memory that is partitioned such that messages associated with bit node groups are consecutively addressed. Alternatively, the LDPC decoder includes a memory that is partitioned such that messages associated with check node groups are consecutively addressed.
