摘要

我们建立了通过猜测随机加性噪声解码（GRAND）的视角来考虑从猜测码字解码（GCD）中提取准确的块和位软输出（SO）的可能性，并且具有最小的额外计算复杂度。分块SO可用于控制解码误检率，而位SO可产生软输入软输出（SISO）解码器，可用于长、高冗余码的高效迭代解码。

Soft-Output Guessing Codeword Decoding

We establish that it is possible to extract accurate blockwise and bitwise soft output (SO) from Guessing Codeword Decoding (GCD) with minimal additional computational complexity by considering it through the lens of Guessing Random Additive Noise Decoding (GRAND). Blockwise SO can be used to control decoding misdetection rate, while bitwise SO results in a soft-input soft-output (SISO) decoder that can be used for efficient iterative decoding of long, high redundancy codes.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
