Query: Generalized Simplified Variable-Scaled Min Sum LDPC decoder for
  irregular LDPC Codes   In this paper, we propose a novel low complexity scaling strategy of min-sum
decoding algorithm for irregular LDPC codes. In the proposed method, we
generalize our previously proposed simplified Variable Scaled Min-Sum
(SVS-min-sum) by replacing the sub-optimal starting value and heuristic update
for the scaling factor sequence by optimized values. Density evolution and
Nelder-Mead optimization are used offline, prior to the decoding, to obtain the
optimal starting point and per iteration updating step size for the scaling
factor sequence of the proposed scaling strategy. The optimization of these
parameters proves to be of noticeable positive impact on the decoding
performance. We used different DVB-T2 LDPC codes in our simulation. Simulation
results show the superior performance (in both WER and latency) of the proposed
algorithm to other Min-Sum based algorithms. In addition to that, generalized
SVS-min-sum algorithm has very close performance to LLR-SPA with much lower
complexity.
