In the early termination of turbo-decoding iterations, stopping criteria are used to minimise the decoding delay without sacrificing performance. However, most stopping criteria have been integrated with low-modulation techniques. To adapt the stopping criteria to high-speed networks, they need to be integrated into high-modulation techniques. Hence, to address this requirement, this research aimed to analyse the performance and robustness of stopping criteria with high-modulation techniques for high data rate transmission contexts. Several stopping criteria, including cross-entropy (CE), the sign-change-ratio (SCR), the hard-decision-aided (HDA) approach and improved minimum descriptive length (IMDL), were integrated and tested using quadrature amplitude modulation (QAM).
