Spectrum Access Scheduling Among Heterogeneous Wireless Systems

Date Added: Oct 2009

The spectrum scarcity problem emerged in recent years. Spectrum access scheduling addresses challenges arising from spectrum sharing by interleaving the channel access among multiple wireless systems in a TDMA fashion. Different from cognitive radio approaches which are opportunistic and non-collaborative in general, spectrum access scheduling proactively structures and interleaves the channel access pattern of heterogeneous wireless systems, using collaborative designs by implementing a crucial architectural component - the base stations on Software Defined Radios (SDRs).
