The aim of this project is the analysis of the performance limits of non-coherent com-munication in two types of wireless networks of practical relevance and the investiga-tion of appropriate transmission schemes for these networks. With non-coherent com-munication we mean that neither transmit nor receive channel knowledge is available at the network nodes. The networks of interest include networks with relays and interfer-ence networks. Preliminary results of our group members show that, under certain as-sumptions, non-coherent communication attains a significant fraction of the perform-ance of coherent communication in the same setup in terms of the achievable sum rate. Therefore, the investigation of appropriate schemes for non-coherent communication is of practical relevance. Additionally, in certain cases, the analysis with the assumption of no channel knowledge gives new insight for the case with channel knowledge. Hence, the work on non-coherent communication can also lead to a better understand-ing of the performance limits of wireless networks in general.

该项目的目的是分析两种具有实际意义的无线网络中非相干通信的性能限制，并研究这些网络的适当传输方案。对于非相干通信，我们的意思是网络节点处不提供发送或接收信道知识。感兴趣的网络包括具有中继的网络和干扰网络。我们小组成员的初步结果表明，在某些假设下，就可实现的总速率而言，在相同设置中非相干通信的性能占相干通信性能的很大一部分。因此，研究非相干通信的适当方案具有实际意义。此外，在某些情况下，假设没有渠道知识的分析可以为有渠道知识的情况提供新的见解。因此，非相干通信的工作也可以帮助我们更好地理解无线网络的总体性能限制。
