Abstract
In this paper, we consider the use of frequency block hopping in the uplink of orthogonal frequency division multiplexing (OFDM) based wireless systems. The hopping block size influences the channel estimation accuracy and thus affects the effective signal-to-noise power ratio (SNR) of the receiver as well as the diversity gain. The hopping block size is optimally determined to minimize the average error probability which is associated with the SNR and diversity gain. Simulation results show that the analytic design is practically applicable to various channel coding schemes.
