基于LDPC码和物理层网络编码的联合信道编码技术

A joint channel coding technology based on LDPC and physical layer network coding

将LDPC信道编码与物理层网络编码结合起来,通过码字叠加的原理,提出了一种新的联合信道编码技术。该技术通过将中继节点处经过网络编码的信号作为冗余码,与原编码信号共同组成联合编码信号,有效降低了通信系统的误比特率,提高了系统传输性能。

By combining the LDPC channel coding technology and the physical layer network coding, and based on the principle of superposition by the code word, this paper has put forward a new joint channel coding technology. Such technology, having treated the network coding signal in the relay node as a redundant code and integrating it with the original coded signal to form a joint coding signal, can effectively reduce the bit error rate and improve the transmission performance.
