- In cognitive cellular networks, secondary users are allowed to use the radio resource owned by the primary system if their interference imposed on the primary users (PUs) is below the predefined thresholds. This paper is significant because it introduces a novel downlink optimization problem and proposes an iterative algorithm to minimizes the cognitive base station transmit power and the induced interference on the PUs, keeping them well below the predefined thresholds. Further reduction on the imposed interference makes new radio resources available to be allocated to a secondary system, thus results in higher secondary system throughput.
