HNN-TE and CTE normalized computational complexity for short channels and varying coded block length assuming $\mathit{O}{\mathit{(}\mathit{N}}_{\mathit{c}}^{\mathit{2}.\mathit{376}})$ matrix multiplication complexity. Blue circle: CTE (BPSK); Black square: CTE (4-QAM); Red circle: HNN-TE - N _c  = 80 (BPSK); Red square: HNN-TE - N _c  = 160 (BPSK); Red diamond: HNN-TE - N _c  = 320 (BPSK); Red down triangle: HNN-TE - N _c  = 640 (BPSK); Red left triangle: HNN-TE - N _c  = 1280 (BPSK); Red right triangle: HNN-TE - N _c  = 2560 (BPSK); Green circle: HNN-TE - N _c  = 80 (4-QAM); Green square: HNN-TE - N _c  = 160 (4-QAM); Green diamond: HNN-TE - N _c  = 320 (4-QAM); Green down triangle: HNN-TE - N _c  = 640 (4-QAM); Green left triangle: HNN-TE - N _c  = 1280 (4-QAM); Green right triangle: HNN-TE - N _c  = 2560 (4-QAM).
