Technical work of the ICT-ACROPOLIS Network of Excellence in its first year

ICT-ACROPOLIS is a new Network of Excellence (NoE) supported by the European Commission´s Framework Programme 7. This paper provides an overview of some of the technical work that has been performed in the ACROPOLIS NoE within its first year. Moreover, it highlights achievements in ACROPOLIS based around phases of the cognition cycle, and some initial inputs to standardization work and contacts with industry. Among the numerous technical achievements covered include methods for out-of-band emissions reduction in secondary NC-OFDM, means of cognitive radio beamforming to secondary users in various scenarios including multihop routing in cognitive radio networks, and pioneering applications for cognitive radio technologies such self organization and interference mitigation in femtocells. It should be noted, however, that this paper only selects some highlights of the work performed; it is not intended to be an exhaustive representation of the work in ACROPOLIS.
