Enabling physical layer techniques for boradband cooperative communication systems

协作通信是一种新的无线通信技术，在这种技术中，网络节点之间相互帮助，实现空间分集。这种新的传输模式承诺在链路可靠性，频谱效率，系统容量和传输范围方面的显着性能增益。现有的协作通信文献主要集中在频率平坦衰落信道模型，这是非常不现实的宽带应用。拟议的研究计划设想合作通信作为下一代高速宽带无线系统的关键使能技术。为此，它致力于宽带协作通信方案的设计，分析和优化，研究与协作协议和中继模式相结合的单载波和多载波传输解决方案。

Cooperative communication represents a new class of wireless communication techniques in which network nodes help each other in relaying information to realize spatial diversity advantages. This new transmission paradigm promises significant performance gains in terms of link reliability, spectral efficiency, system capacity, and transmission range. The existing literature on cooperative communication has so far mainly focused on the frequency-flat fading channel model which is highly unrealistic for broadband applications. The proposed research program envisions cooperative communication as a key enabling technology for next-generation high-speed broadband wireless systems. Towards this purpose, it addresses the design, analysis, and optimization of broadband cooperative communication schemes, investigating single-carrier and multi-carrier transmission solutions integrated with cooperation protocols and relaying modes.
