Abstract
The error detection performance of CRC coding in LTE with general two-level early stopping algorithms for turbo decoding is investigated. Analytical models for the probability of block error and undetected block error at the code block and transport block levels were developed. Simulations were used to verify the model for shorter CRC lengths and block sizes. The analytical models show the setting of 24-bit CRCs in LTE allows low-complexity, robust and reliable early stopping algorithms to reduce turbo decoding complexity.
