Abstract :
Error models characterize the statistics of bursty error sequences encountered in digital wireless channels and are therefore, useful for the cross-layer design of wireless networks. In this paper, target error sequences are generated by computer simulations of multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) systems. A corresponding generative model is then developed based on a properly parameterized and sampled deterministic process followed by a threshold detector and two parallel mappers. Simulation results indicate that the developed deterministic process based generative model (DPBGM) enables us to approximate very closely the characteristics of target error sequences with respect to all the interested burst error statistics.
