This chapter presents representative examples of design problems in wireless communications using evolutionary algorithms (EAs). The following design problems are dealt with: peak-to-average power ratio reduction in OFDM systems, antenna selection in MIMO systems, cognitive radio engine design, spectrum allocation in cognitive radio networks and the optimization of wireless sensor networks.
