Theoretical Analyses of Data Communications Integrated into Cordless voice Channels

摘要

Dynamic integration of data into voice channels of 2nd generation cordless systems provides an effective channel utilization. This paper proposes and theoretically examines an Inhibit and Random Multi Access (IRMA) protocol for data terminals in the integrated voice and data system. Analytical expressions are derived to quantify the effect of data inhibition on its performances, i.e. throughput and delay for both infinite and finite population model. We investigate the data performance in two extreme situations: 1. No voice load and 2. Full voice load. The numerical results indicate that a comparable performance can be achieved.
