A novel genetic algorithm application is proposed for adaptive power and subcarrier allocation in multiuser OFDM systems. The proposed method is compared with Eshan's [2] power and subcarrier allocation algorithm and Wang's modified genetic algorithm [23]. Our method has fast convergence and can handle large allocations of subcarriers to users without(More)
– Orthogonal Frequency Division Multiplexing is a promising technology for high data rate transmission in wideband wireless systems for achieving high downlink capabilities in the future cellular systems. To minimize the overall transmit power, the genetic algorithm approach was proposed for adaptive subcarrier and bit allocation based on channel state(More)
