A Joint Adaptive Scheme for Iterative Turbo Decoding
摘要
Abstract
Iterative decoding can provide an excellent performance for Turbo codes, but it also brings on decoding delay. To reduce it, we propose a joint adaptive optimization scheme. We use external adaptive iterative criteria to determine the number of iterations. The stopping criteria is further used in the internal iterative. The average iteration number of the joint adaptive scheme is smaller than the single external or internal iteration scheme, while the frame error rate performance is similar to the external adaptive iterative scheme.关键词
