摘要:

相比基于 XOR 的网络编码协作方案,网络乘积编码协作方案是一种更有前景的抗衰落技术,既能明显地提高误码率性能,又能减少网络中所需要的中继个数。基于协作多址接入场景设计了一种多元网络乘积编码协作方案,通过深入的理论分析表明所构建的网络乘积码能实现近似高斯权重分布,从而能明显地提高误码纠错率。仿真结果也验证了该协作方案相比传统网络乘积码能获得更高的误码率性能。

Abstract:

Network product coding, a promising and anti-fading technology, can not only outperform the conventional XOR based network coding scheme in bit error rate performance, but also reduce the number of relays required in the network. A multi-component network product coding scheme was designed for cooperative multiple access scenarios. Analytical results are developed to show that the constructed network product codes are able to realize asymptotically Gaussian weight distribution which is desirable to good error-correcting ability. Simulation results are also provided to demonstrate the performance of the proposed scheme.

Key words: network coding, product coding, weight distribution, distributed encoding, high rate coding
