This is an encoder, not a decoder. It also just dumps the results to console in an unusable format, one quoted symbol per line, but that's what all the other example do too. Regardless of whether everyone else is doing it that way, it means that the output of your encoder can't ac...
'whole'— Output the whole LDPC codeword, including information bits and parity-check bits. The number of rows that the function outputs equals the value of theBlockLengthproperty for the inputencodercfg. 'parity'— Output only the parity-check bits. The number of rows that the function outpu...

这里记录一下 1.首先将TAppDecoder设置为启动项 2.在属性界面中添加编码生成的.bin文件,同时给将要解码生成的yuv文件命名。 -b 表示输入的bin文件,-o表示输出的yuv文件 3.把编码生成的.bin文件放在工作目录下即可。 4.编译成可执行文件,点击调试。......
SC全称successive cancellation decoder,即连续消除译码。SC译码采用蝶形算法,通过递归的方式进行串行解码,其优点在于算法复杂度较低,缺点是无法进行并行解码(并行解码可以提高解码速度)。对于polar code的解码,还有几种常用方案:BP解码、SCL解码、SCAN解码等,本系列我们重点来介绍SC译码。
When you use either the xception (Deep Learning Toolbox) or mobilenetv2 (Deep Learning Toolbox) base networks to create a DeepLab v3+ network, depth separable convolutions are used in the atrous spatial pyramid pooling (ASPP) and decoder subnetworks. For all other base networks, convolution ...
