摘要
将网络编码与合作中继传输中的解码转发或放大转发相结合,提出了2种新的数据传输方式;推导了这2种传输方式下数据速率的表达式;理论推导和仿真结果表明,与通常的存储转发及单独的网络编码传输方式相比较,所提出的这2种传输方式可以较大地提高网络的数据传输速率.
Two new data transmission protocols combining Network Coding with decode-and-forward(DF) or amplify-and-forward(AF) of Cooperative Relay are proposed. Expressions of data rate for these two protocols are derived.Theoretical derivation and simulation show that compared with conventional store-and-forward and independent Network Coding,the data transmission rate of the network is greatly improved by these two protocols.
