摘要
结合联合网络信道编码的思想设计了一种应用于多址接入中继信道环境中的基于Turbo码的联合网络信道编码方案,详细介绍了方案中继节点编码和基站处译码的实现。将该方案与点对点传输方案、异或操作网络编码传输方案进行仿真比较,仿真结果表明,该方案能更加有效地利用中继信道传输的额外冗余信息,明显改善了无线通信系统的性能。
According to idea of joint network-channel coding, a scheme of joint network-channel coding based on Turbo code applied to multiple access relay channel was proposed, and implementation of relay node encoding and base station decoding was introduced in details. The simulation of the scheme was compared with the point to point scheme and XOR operation network-channel coding scheme. The simulation results show that the scheme can sufficiently use additional redundancy from the relay channel, and significantly improve performance of wireless communication systems.
