Abstract: Aiming at the interference power threshold of the primary user (PU) in the cognitive radio network (CRN), transmission rate limit of the secondary user (SU) and the signaltointerferencenoiseratio (SINR) requirement, we proposed a learning traditional particle swarm optimization (LTPSO) algorithm, in which the evaporation factor was set according to the particle swarm learning factor, a new particle swarm memory form was established, and the fitness values were screened proportionally. The simulation results show that the LTPSO algorithm achieves better optimization results.
Key words: cognitive radio, power allocation, particle swarm optimization (PSO) algorithm
