Abstract :
Development of novel signal processing and communication techniques for 3G wireless systems is motivated by high data rate service requirements. These techniques include adaptive modulation and transmitter antenna diversity. In rapidly time variant channels, these methods need the knowledge of future fading conditions. Thus, they require accurate long range fading prediction. We investigate three combined adaptive modulation and transmitter diversity schemes in conjunction with our previously proposed long range channel prediction (LRP) algorithm. It is demonstrated that the novel combined schemes can achieve higher data rates than the conventional adaptive modulation methods when aided by the LRP
