文章在上行协作OFDM传输系统下提出了一种基于机会网络编码的子载波抑制方法,介绍了离散子载波抑制和合并子载波抑制这两种方法的区别在于系统所能实现的性能和节点间交换数据所需的信令开销。仿真结果显示这两种方法相比传统的上行传输有较低的误比特率,提高了系统的可靠性。
This paper proposes a subcarrier suppression method based on opportunistic network coding in uplink cooperative OFDM transmission system. The differences between discrete subcarrier suppression and combined subcarrier suppression are described in terms of the system performance and inter-node exchange The signaling overhead required for the data. Simulation results show that these two methods have a lower bit error rate than the traditional uplink transmission and improve the system reliability.
