| 摘 要： | 空间位置的不同是无线通信中区分不同用户的最重要特征,针对多点协作通信网络提出一种利用随机选择冗余中继转发信号的无线信道加密方法。该方法在中继节点空间位置固定的情况下,随机选取中继节点以达到信道加密的目的;同时通过调整中继节点发送信号的相位,使得发送信号的能量在合法用户处聚集。仿真结果表明,该无线信道加密方法在保证合法用户正常接收信号的情况下,大大降低了被非法用户截获的概率。

| Abstract: | Spatial location is the most important feature for distinguishing different users in wireless systems.A new method using redundant relays for secure transmission in cooperative wireless network is proposed in this paper.This method randomly selects the redundant relaying signals in radio channel for encryption when the spatial location of relay nodes is fixed.The transmitted signals are also concentrated on the target receiver by adjusting the signal phases of the relay nodes.Simulation results show that th... |
