Sensing-then-transmission slot scheduling optimization for opportu-nistic spectrum access under the interference constraint of primary us-ers

Show other versions (1)

A sensing-then-transmission slot scheduling scheme for opportunistic spectrum access under the interference constraint of primary users (PU) was proposed.First,the throughput of the cognitive radio system (CRS) with channel handoff mechanism and the interference ratio to PU were deduced.An optimizat...
