Cognitive radio(CR) is a potential technology for efficient utilization of under-utilized spectrum via spectrum sensing. CR users should move from current allocating channel to empty channel to avoid the interference to the primary user if the primary user is allocated that channel. Thus, CR system cannot support the CR user's QoS(Quality of Service). In this paper, we propose a dynamic frequency selection method based on Genetic Algorithm(GA) with ranking in UHF personal/portable system, which is to find the optimization channel for satisfying various CR user's needs such as throughput maximization and interference minimization. And, we propose the GA which determines the best configuration for CR communication systems. The computer simulation results show that the proposed method guaranteed the primary user's optimized solution for various channel status.
