摘　　要：网络编码技术被引入无线通信中,充分利用了无线通信网络的广播特性和数据信息业务的双向特性,在中继节点把不同信源节点发送的干扰用编码关系进行信息融合,提升了无线通信网络系统的吞吐量和通信效率。无线通信传输环境有很多不确定的因素,为了保证传输的可靠性,引入了分集的概念,通过传送多个统计独立的信号以供译码。无线通信环境中,分集技术是一种有效的抗衰落方法。The network coding technology is introduced in the wireless communication, make full use of the characteristics of thewireless communication network bidirectional broadcast properties and data information service, the interference of different sourcenodes send for coding relationship for information fusion at the relay node, improve the throughput and the communication efficiencyof wireless communication network system. The wireless communication environment, there are many uncertain factors, in order toensure the reliability of the transmission, introduced diversity concept, through the transmission of multiple statistically independentsignals for decoding. In the wireless communication environment, diversity is an effective anti fading method.
