摘要：

A simulation tool was developed to evaluate the performance of cognitive radio systems based on the spectral efficiency achieved. The tool utilizes measurements of spectrum occupancy by primary users as input data. A description of the measurements setup and methodology is presented, as well as the consolidated results of spectral occupancy in frequency bands from 144 MHz to 2690 MHz at one site in Rio de Janeiro, Brazil. Simulation results indicate that cognitive radio efficiency is strongly dependent on occupancy fragmentation. An allocation scheme to improve performance of cognitive radio systems in fragmented frequency bands is proposed.
