摘要:

针对配置多天线的上行无线中继网络,提出了一种基于网络编码的传输方案,从遍历容量和中断概率的角度对其进行了分析,并与基于同样拓扑的普通中继分集方案和正交空时编码方案进行了性能比较结果表明,网络编码可以有效地改善多天线上行无线中继网络的性能,且天线数越多,性能越好

Abstract:

A network coding based transmission scheme is proposed for multiantennas based uplink wireless relay networks. Its performance is evaluated from the perspective of ergodic capacity and outage probability, and compared with ordinary relay diversity scheme and with orthogonal space time coding scheme. Calculations show that network coding can effectively improve the performance of multiantennas based uplink wireless relay network, and the more the antennas, the better the performance.

Key words: multiantennas, network coding, wireless relay network
