| 摘 要： | 该文在双向中继信道中基于网格编码调制(Trellis Coded Modulation,TCM)提出了一种信道编码与物理层网络编码的联合实施机制.该机制采用TCM,将编码和调制统一考虑,提高了编码序列的自由距离,从而获得更高的编码增益.此外,利用卷积码和MAC-XOR网络编码的线性性质,使得中继节点只要直接估计网络编码...

| Abstract: | A new scheme of joint channel coding and Physical layer Network Coding(PNC) is proposed for multiple-access channel based on Trellis Coded Modulation(TCM) in the Multiple Access Control(MAC) stage of the investigated two-way relay scenario.As a result of the adoption of TCM that combines channel coding with modulation,the scheme improves the free distance of the coding sequence,thus more encoding gain is obtained.In addition,the proposed scheme takes advantage of the linearity of convolutional code and MAC-... |
