Autonomous SIR-based power control for a TDMA radio system
Sirikiat Lek Ariyavisitakul · 2002
Power control based on signal-to-interference ratio (SIR) has been proposed as a technique for managing cochannel interference due to frequency reuse in a time-division multiple access (TDMA) radio system. Early studies have focused on SIR balancing approaches that require centralized control for global power adjustment and/or associated channel reassignment. This paper investigates the achievable performance of an autonomous power control technique which relies only on a simple fixed-step feedback adjustment algorithm. Simulation results indicate that this simple power control technique can perform nearly as well as ideal SIR balancing/call removal, yielding a possible increase in spectrum efficiency of at least 3 times compared to a system without power control. This work is targeted toward understanding the traffic capacity and deployment implications to local exchange networks of wireless technology alternatives that could provide access to those networks.>
