Table 2 The usage number of HDD in each syndrome-based decoding algorithm

From: An advanced low-complexity decoding algorithm for turbo product codes based on the syndrome

 The number of required HDD operations
SBDA-IH1=Iave×n×2p×(1−λzero)
SBDA-IIH2=Iave×n×{2p−1(λDESS+λSESS)+λSEHS}
proposedH3=Iave×n×{2p−1(λDESS+λSESS)+(λSEHS+λDEHS)}
