Effect of fixed and interference-induced packet error probability on PRMA

For a voice user in PRMA, a packet header error leads to the loss of slot reservation while a packet data error only causes a rejection of the transmitted packet. We use equilibrium point analysis and a path enumeration technique for signal flow graphs to analyze the effect of voice packet header and data errors on the performance of PRMA. The technique provides an improvement over the solutions previously suggested in literature. We also extend the analysis to model the effect of cochannel inter-cellular interference and error correction coding on PRMA over fading channels. Analytically obtained results for fixed packet error rates and for packet error rates that depend on the co-channel inter-cellular interference in the system are presented. The limitations of the analytical technique are also discussed
