Space alternating generalized maximum-likelihood based low-complexity list detection algorithm

Tongxin xuebao, 2016
A space-alternating generalized maximum-likelihood (SAGL) list detection algorithm with lower-complexity for V-BLAST systems was proposed. The sub-detector involved in the proposed list detection algor hm consisted of sim-plified maximum-likelihood (SML)

Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability

IEEE Access, 2019
A polar code with repeating bits (RB polar code), where a part of frozen bits only repeat their preceding information bits, is proposed. In the code construction, we propose cluster pairwise error probability (CPEP) to measure the competitiveness of the ...

Design of concatenated Hash-Polar code based on segmented CRC code

Dianxin kexue, 2022
As a linear block code, the polarization code has a lower coding complexity and a definite structure, but when it has a short or medium code length, the performance will be reduced.A design method of concatenated HashPolar codes based on segmented cyclic
