Query: Hybrid Decoding of Finite Geometry LDPC Codes   For finite geometry low-density parity-check codes, heavy row and column
weights in their parity check matrix make the decoding with even Min-Sum (MS)
variants computationally expensive. To alleviate it, we present a class of
hybrid schemes by concatenating a parallel bit flipping (BF) variant with an
Min-Sum (MS) variant. In most SNR region of interest, without compromising
performance or convergence rate, simulation results show that the proposed
hybrid schemes can save substantial computational complexity with respect to MS
variant decoding alone. Specifically, the BF variant, with much less
computational complexity, bears most decoding load before resorting to MS
variant. Computational and hardware complexity is also elaborated to justify
the feasibility of the hybrid schemes.
