中文摘要： 2006年提出的物理层网络编码（PNC）技术进一步提高了双向中继网络的吞吐量，得到了人们的广泛关注。然而后续的研究大多基于线性调制方式，如PAM、PSK和QAM等。连续相位调制（CPM）是一种恒包络的非线性调制方式，具有其它调制方式难以比拟的频谱效率和功率效率。本项目将CPM技术应用于无线双向中继信道，研究基于CPM的物理层网络编码方案，即CPM-PNC，为高速通信及其传输理论提供崭新的视角和方法，具有一定的理论及现实意义。. 本项目拟在无线双向中继网络中：1）研究CPM-PNC系统的信号检测方案及性能分析；2）研究联合信道编码-CPM调制-物理层网络编码系统的设计及优化；3）在频率选择性衰落信道下研究联合OFDM技术的CPM-PNC方案，分析论证其可行性，以推进新型高效通信体制的探究。

英文摘要： Physical-layer network coding (PNC), proposed in 2006, can further increase the throughput of a two-way relay channel (TWRC). It has gained much attention in recent research. As a matter of fact, most of previous works primarily focus on the linear modulation methods, such as PAM, PSK and QAM. Continuous phase modulation (CPM) is a non-linear digital modulation scheme with constant envelope. It contains excellent spectral and power efficiency comparing with other modulation schemes. In this project, we study the application of CPM to a TWRC with PNC. The new scheme, i.e., CPM-PNC, provides a new viewpoint for high speed communication and transmission. So there will be significant practical and theoretical meaning.. The following contents about CPM-PNC in a TWRC will be covered in this project. Firstly, we will investigate the signal detection and performance analysis of the CPM-PNC system. Then, the design and optimization of the new scheme of joint channel code, CPM and PNC will be investigated. Finally, we will study the CPM-PNC scheme with OFDM technology over frequency-selective fading channels and analyze the feasibility, to promote the research of new style high spectral communication system.
