在多年致力于移动的无线电网络的物理层的优化的研究活动之后，似乎焦点部分地转向系统和应用级工程和优化，以改善无线通信的性能。在这一研究领域，科学出版物目前正在介绍新的课题。它们中的大多数不仅旨在逐步改进当前的系统，而且旨在为下一代无线和移动的系统提供上级容量、频谱效率和灵活的操作。这可以例如通过扩展系统带宽并推高传输速率、通过协调相邻小区之间的无线电资源以减少密集重用蜂窝网络中的干扰、通过将自组织网络组件引入蜂窝网络、通过将无线电资源分配给蜂窝网络来实现。并通过引入智能天线技术进行基于空间复用的传输。本专题中包含了一组解决这些问题的系统级相关论文该问题是根据2007年4月1-4日在法国巴黎举行的第13届欧洲无线会议上的一系列口头报告汇编而成的。基于所选最佳论文的高科学质量，2007年电子战技术计划委员会邀请作者开发其原始工作的扩展版本。特刊的内容是经过严格的同行审查，根据电信年鉴的规则，这一选择的结果。
After many years of research activity devoted to the optimization of the physical layer of mobile radio networks, it appears that the focus is shifting in part towards system and applications level engineering and optimization, for an improved performance of wireless communications. In this field of research, new topics are currently being introduced in scientific publications. Most of them aim not only at incrementally improving current systems, but also at providing superior capacity, spectral efficiency and flexible operation to next generation wireless and mobile systems. This can be achieved, eg, by extending the system bandwidth and pushing up the transmission rate, by coordinating radio resources across adjacent cells for reduced interference in dense re-use cellular networks, by introducing ad-hoc network components to cellular, and by introducing smart antenna technology for spatial multiplex based transmissions.A representative set of system level related papers addressing these subjects is contained in this special issue, which has been assembled from a set of oral presentations made at the 13th European Wireless Conference, Paris, France, April 1–4, 2007. Based on the high scientific quality of the selected best papers, the Technical Program Committee of EW 2007 has invited the authors to develop extended versions of their original work. The content of the special issue is the result of this selection, after strict peer reviewing according to the rules of Annals of Telecommunications.
