摘　　要：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 proposed a strategy of subcarrier suppression and opportunistic network coding for uplink cooperative OFDM transmission system,with an introduction of two subcarriers suppression methods and their differences in the performance achieved and the amount of signaling required for nodes to exchange.Simulation results show that the two methods have a better performance than the conditional scheme on the term of Bit Error Rate（BER）.Meanwhile,the reliability of the system has enhanced.
