【摘要】 提出一种TPC自适应迭代译码算法。从接收到的软信息估算信道的信噪比;根据信噪比选择最优的软译码迭代因子,将迭代因子与软信息送入SISO迭代译码器;检测每次SISO译码器的输出,达到迭代终止条件即结束译码。提出的自适应迭代译码方法大大地增强了译码器的灵活性,动态的选择译码策略,尤其在低噪声信道下有效地降低了译码的功耗。更多还原

【Abstract】 This paper proposes an adaptive decoding algorithm for Turbo product code.It firstly calculate the gross SNR from soft input,and then determine the best factor for SISO iterative decoding module,finally verify the output of SISO iterative decoding module,if the termination condition is meet it stop the decoding process.The adaptive decoding algorithm enhances the flexibility of traditional decoding algorithm,and it cost less power compared to fixed iterative decoding algorithm especially when the SNR is high.更多还原
