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.
