Abstract
The model of cognitive relay channel is defined and analyzed. Under the constraint of protecting the primary user´s transmitting rate and with the relaying strategy being decode forward with parallel codes, the capacity of cognitive relay channel is computed. Based on the discussion of cognitive relay channel, relaying strategies in cognitive network are proposed. Simulation results show the feasibility of cognitive relay and the superiority of relay transmission in cognitive scenario.
