Unfortunately it requires relatively high decoding complexity compared to successive cancellation decoding. To remedy high complexity problem, early termination BP algorithm was proposed which requires additional complexity for stopping criteria test. In this paper, we propose low-complexity early termination detectors based on the characteristics of log-likelihood ratios generated within BP detectors. The proposed detectors offer identical performance with lower complexity compared to conventional detectors." }
