Performance Analysis of a Cooperative Network Coding Technique Based on Space-Time Code
一种基于空时码的协作网络编码技术及其性能分析

A Cooperative Network Coding technique based on Space-Time code (ST-CNC) is proposed, which combats channel fading and improves resource efficiency and network throughput. A close form expression for theoretical Bit Error Rate (BER) performance of the information exchange in two-hop chain network is derived and its diversity gain and network coding gain is analyzed. The numerical results show that the BER performance of ST-CNC outperforms the traditional strategies with distinctive gains. Furthermore, the simulation results coincide with the theoretical results well.
