摘要

提出了一种适用于协同无线网络的频谱高效上行通信方法。在蜂窝控制点对点(CCP2P)协作无线网络中,移动设备通过蜂窝链路与基站逻辑连接,同时通过短距离链路与相邻移动设备逻辑连接,形成协作集群。到目前为止,蜂窝链路上的物理通信和短距离链路上的物理通信在时间或频率上是分开的。在此技术水平之外,我们开发了一种称为不对称调制的方法,其中移动设备产生的信号以相同频率甚至同时向基站和相邻设备传输。信号以这样一种方式组成,它对相邻设备的意义与对基站的意义不同。当基站接收到粗粒度信息时,相邻设备接收到的是细粒度信息。分析和仿真结果表明,不对称调制既不会降低码元误码率性能,也不会增加每比特平均能量,从而提高了频谱效率,降低了数据排队延迟。

Asymmetrical Modulation for Uplink Communication in Cooperative Networks
In this paper a spectrum efficient uplink communication method for cooperative wireless networks is presented. In cellular controlled peer to peer (CCP2P) cooperative wireless networks the mobile device is logically connected over cellular links with the base station and simultaneously over short-range links with neighboring mobile devices to form cooperative clusters. So far the physical communication over cellular links and over short-range links are separated in time or in frequency. Beyond this state of the art, we exploit a method, referred to as asymmetrical modulation, where a mobile device is generating signals that are conveyed towards the base station and the neighboring devices in the same frequency and even at the same time. The signal is composed in such a way that it has different meanings for the neighboring devices than the base station. While the base station is getting the coarse information, the neighboring devices are getting the fine grained information reading between the lines. Our analytical analysis and simulation results show that asymmetrical modulation can improve the spectrum efficiency and reduce the data queuing delay with neither degrading the symbol error rate performance nor increasing the average energy per bit.
