由于本方案中SISO模块将时分复用作为两个分量译码器,对应于一次译码迭代的两个半迭代过程。因此图4中的Decoder_num为低时,SISO模块作为第一个分量译码器,进行第一个半迭代运算;Decoder_num为高时,SISO模块作为第二个分量译码器,进行第二个半迭代运算。每次半迭代产生的对数似然比信息作为下次半迭代的先验信息。用两...
Abstract: In order to satisfy the high-performance and low-power dissipation requirement in wireless communication, this paper proposes a low storage capacity and low-power dissipation Turbo decoder architecture based on the reverse recalculation and linear estimation by changing the storage method of ...

中山大学微电子科学与技术学院胡建国教授团队针对NB-IoT通信标准的低功耗Turbo编码与解码展开研究,相关成果以“面向NB-IoT的低功耗Turbo编解码电路设计”(Design of Low-Power Turbo Encoder and Decoder for NB-IoT)为题,发表在Chinese Journal...
图7中,译码器首先根据帧长设置初始化交织图样,然后对系统码字解复接,得到信息序列(ys)、校验位1(yp1)及校验位2(yp2),与外信息(L_all)一起输入子译码器进行SISO译码运算,迭代6次以后判决得到译码结果(decoderout)。 设置不同的信息帧长,经多次仿真验证,均能正确实现编译码功能。将程序下载配置到EP3SL150F1152...
