The analysis of a birth-death process using the z-transform was recently reported for processes having fixed transition probabilities between states. The current report extends that analysis to processes having transition probabilities that can differ from state to state. It is then shown that the model can be used to study practical queuing and birth-death(More)
The inherent immunity of OFDM to multipath limitations comes with the price of increased sensitivity to inaccuracies in the reference frequency. A carrier offset at the OFDM receiver causes losses in subcarrier orthogonality, and thus introduces inter-channel interference (ICI) which degrades the system performance. In mobile communication technology,(More)
