摘要
Abstract
In this paper a physical-layer network coded two way relay system applying Low-Density Parity-Check (LDPC)codes for error correction is considered;We first group the existing schemes for physical network coding into two generic schemes, and consider the joint channel-decoding and network-encoding algorithms based on denoise-and-forward (DNF)protocol;In the theory of optimal detection,we fetch out Log-domain decoding algorithm over the Galois field GF (4); Simulation results show that the algorithm outperforms other recently proposed schemes. Finally,the effect of relative carrier phase offset on the system performance over the complex channel is investigated,and the solution is proposed.关键词
