基于极化格码设计的计算转发方案
A Compute-and-Forward Scheme Based on Polar Lattice Codes
摘要
Abstract
A novel transmission scheme based on polar lattice codes is proposed for Gaussian two-way relay channels.This scheme leverages the linear properties of polar lattice codes,enabling the relay node to directly decode linear combinations of signals from two users,thereby reducing the number of decoding and forwarding operations at the relay node.Additionally,owing to the excellent error-correction capability and coding efficiency of polar lattice codes,this approach demonstrates potential performance close to the capacity limit of compute-and-forward strategies,even at moderate coding complexities.Numerical simulations confirm that the proposed scheme significantly enhances communication efficiency in high signal-to-noise ratio scenarios,achieving performance comparable to that of point-to-point additive white Gaussian noise channels.关键词
