Cross-Layer Design in Dynamic Spectrum Sharing Systems

Date Added: Aug 2010

The authors consider a dynamic spectrum sharing system consisting of a primary user, whose licensed spectrum is allowed to be accessed by a secondary user as long as it does not violate the prescribed interference limit inflicted on the primary user. Assuming the Nakagami-m block-fading environment, they aim at maximizing the performance of secondary user's link in terms of Average Spectral Efficiency (ASE) and error performance under the specified Packet Error Rate (PER) and average interference limit constraints.
