Future Gigabit Systems: Towards 4G and Cognitive Radios

Next generation wireless systems’ are supposed to reach ambitious targets in terms of data rate and spectrum efficiency, which can be fulfilled only if a sufficient degree of intelligence and adaptivity can be put into future radios. This tutorial will address a number of intelligent and autonomous techniques that can be implemented in future wireless systems to realize such efficient high rate networks.

After a general introduction on future Gigabit/s systems, some advanced PHY and RRM techniques suitable for achieving “real” 4G targets in terms of data rate and spectral efficiency will be given, keeping especially an eye on smart and flexible design. The concentration will be on multi-antenna techniques, cognitive radios, advanced spectrum management, adaptive scheduling etc. Specifically, challenges and benefits related to flexible and smart spectrum utilization, spectrum sharing and cognitive radio techniques will be touched, as complementary and evolved technologies with respect to the above-mentioned PHY and RRM architectures.
