摘要

<FONT face=Verdana>转接节点的选择是协作通信中的一个比较重要的问题.在许多实际情况中并不是所有节点都参与转接，本文研究了在所有潜在的转接节点中任选一个节点作为转接节点的协作分集方法，推导了这种协作分集方法中断概率的上界和下界.理论计算和仿真结果表明该协作分集的中断概率的上界基本不随潜在的转接节点的数目的增加而变化，而下界却随潜在的转接节点的数目的增加而显著降低.

Abstract

<FONT face=Verdana>The relay selection plays a very important role in cooperative communication systems. In many practical scenarios not all nodes between the source and the destination which can decode information from the source take part in relay

here we propose a cooperative diversity method which randomly selects a node from a set of available relays to forward information towards the destination and then analyze the outage probability of this method. Theoretical analysis and simulation results demonstrate that the upper bound of this outage probability almost does not vary to the number of potential relay nodes

but the bottom bound of this outage probability becomes much smaller as the number of potential relay nodes increases.
