  In this letter, we propose a reliability-based windowed decoding scheme for
spatially-coupled (SC) low-density parity-check (LDPC) codes. To mitigate the
error propagation along the sliding windowed decoder of the SC LDPC codes, a
partial message reservation (PMR) method is proposed where only the reliable
messages generated in the previous decoding window are reserved for the next
decoding window. We also propose a partial syndrome check (PSC) stopping rule
for each decoding window, in which only the complete VNs are checked.
Simulation results show that our proposed scheme significantly improves the
error floor performance compared to the sliding windowed decoder with the
conventional weighted bit-flipping (WBF) algorithm.
