联合网络信道编码可被有效用于双向中继信道的去噪转发协议(DNF)。文章针对典型的复信道模型,在DNF协议下分析了信道相对相位对系统性能的影响。另外,文章基于联合网络信道编码的最佳检测方案提出了一种简化的检测方案。分析和仿真表明:所提出的简化方案实现复杂度低,性能非常接近最佳检测器。
The joint network channel coding can be effectively used for the de-noising forwarding protocol (DNF) of two-way relay channels. Aiming at the typical complex channel model, this paper analyzes the influence of channel relative phase on system performance under DNF protocol. In addition, the article proposes a simplified detection scheme based on the best detection scheme of joint network channel coding. The analysis and simulation show that the proposed scheme is of low complexity and very close to the best detector.
