【摘要】 为了降低Turbo码的译码时延,这里从Turbo码迭代译码过程作为一非线性动态系统的观点出发,提出了一种有效的迭代译码停止判据,仿真结果表明这种停止判决方法减少了Turbo码译码的平均迭代次数,同时译码性能没有降低.更多还原

【Abstract】 In order to reduce the delay time of Turbo decoding,we propose an efficient stopping criterion from the perspective that the turbo iterative decoding process which can be considered as a nonlinear dynamic system.The simulation experiment shows that the new criterion can reduce the number of decoding iteration while the BER performance was not degraded.更多还原
