Low-Complexity LDPC Decoding Algorithm Based on Layered Vicinal Variable Node Scheduling

Algorithm 1

LWNS scheduling.

1: Initialize all , and Itermax

2: for to Itermax do

3:   for every ordered based on the influence metric do

4:     for every do

5:      for every do

5:         Generate and propagate

6:      end for line 5

7:     end for line 4

8:    for every do

7:   Calculate

8:   Generate and propagate

9:    enf for line 8

10:   Calculate

11:   end for line 3

12: if stopping rule is not satisfied then

13: Go back to line 3

14: end if

15: end for line 2
