摘要

为设计出可近容量限传输且能普适应用于慢、快衰落信道下的编码协作方案，研究了基于卷积LDPC码的编码协作。基于卷积LDPC码的凿孔算法构造出可2路传输的分码字，实现编码协作，并在第二帧分码字传输阶段引入了空时传输进一步提升编码协作的性能。仿真验证了所提方案的有效性。

Abstract

To design a scheme that can approaching the capacity 1imitation transfer，and genera11y app1ied to s1ow and fast fading，the coded cooperation based on LDPC convo1utiona1 codes was studied.First1y，based on LDPC convo1utiona1 codes，the coded words were divided into two parts by puncturing a1gorithm to achieve coded cooperation.The space-time transmission was introduced into the second frame of coded cooperation to further improve the performance of the system.Simu1ation resu1ts show the effectiveness of proposed scheme.
