| 摘要: |
| 分析了用于点对点和点对多点通信链路协同通信技术的使用。通过设计一个简单的中
继模型来分析多节点协作通信方式。运用放大转发、解码转发协作协议，分别计算比较了链
路
的效率和同步性，以通过不同的中继协议来仿真中断概率与频谱效率的理论性能。
仿真分析表明，完全功率分配比平均功率分配方法提高约3 dB的信噪比。 |

| Abstract: |
| The use of cooperative communication techniques fo
r pointtopoint and pointtomultipoint communication links is presented. A
simplified single relay model is designed to analyse the multinode sc
enarios. The amplifyandforward(AF) protocol and decodeandforward proto
col are applied to compute the efficiency and synchronization of the
link so that the theoretical performance of
outage probability versus spectral efficiency can be simulated based on differen
t relay protocols.
The simulation analysis shows power distribution method can improve about 3 dB
SNR than the average power al
location method. |
