Throughput of the 1x EV-DO system with various scheduling algorithms

Abstract

The average sector throughput of the popular 1x EV-DO system with three different scheduling algorithms is mathematically analyzed for a multicell system with lognormal shadowing. The scheduling algorithms considered are round robin, equal latency, and relative fairness. The trade off between throughput and latency among the three scheduling algorithms is illuminated by the analysis, since the key design parameters are identified. From numerical examples, it is shown that the average throughput in a typical urban area is around 600-800 kbit/s. The results of this paper will help engineers do cellular planning and reliably predict throughput for 1x EV-DO and other data-based cellular systems.
