双向中继网络中的物理层网络编码方案

双向中继系统中的物理层网络编码可以有效的提高无线中继网络的吞吐量,受到了普遍关注。为了提升物理层网络编码在无线信道中的性能,提出了联合网络编码与信道编码设计思想。在联合信道编码-网络编码思想基础上,提出了一种结合LDPC信道编码和网络编码的线性性质来提升网络编码在双向中继系统中的性能,并最后给出该方案的误码率仿真图。

A Physical Network Coding Scheme for Two-Way Relay Network

Physical network coding （PNC） is attracting more and more attention because of its ability to improve the throughput of wireless network significantly. To improve the performance of PNC on wireless channels, joint design of PNC and channel coding are considered. This paper proposed a joint network coding and LDPC scheme which the linearity of LDPC code and network coding are combined together to improve the performance of network coding in wireless channels, and BER simulation of this scheme is presented.
