Traditional and Reacquisition-Induced Outage Prediction for DSSS and OFDMA Systems on Multipath Fading Channels

Reacquisition-induced outages continue to increase in importance for advanced systems that employ MIMO antennae, space diversity and adaptive equalizers to mitigate the effects of multipath fading. In addition to the channel model, the fading dynamics plays a key role; hence we provide a novel means of simulating random processes in which we can control the spectra, as well as the probability distributions. We formulate a Markov model from which we derive steady-state predictions of reacquisition-induced outages. The utility of these are illustrated via the simulation of a variety of wireless communication scenarios, which also demonstrate conditions under which reacquisition is the dominant source of outages.
