Acceleration of s-polar ecc throughput by scheduler

Abstract

A method of simplified successive cancellation list (SSCL) error decoding of S-polar codes includes representing an S-polar code as a perfect binary tree; providing a node v a vector αof soft information from a parent node; computing a vector αof soft information for a left child of node v; providing node v with a vector βof hard decisions from the left child and using it with αto create a soft information vector αand passing it to a right child of node v; providing node v with a vector βof hard decisions from its right child and using it with βto create a hard decision vector, βof hard decisions, and passing it to its parent node; updating, when v is a ileaf of the perfect tree, two path metrics, and selecting paths obtained by expanding current paths with a lowest path metric.
