Power Control for Packet Voice Service with Application to EDGE Wireless System
01 January 2004
Using the EDGE system with cyclic frequency hopping as an example, we examine how a power control algorithm based on interference prediction by Kalman filter can be applied to packet voice service in future TDMA wireless networks. We propose an associated set of signaling messages and analyze the performance of the power control for packet voice applications. Our results show that the power-control method significantly improves the spectral efficiency by enabling the 1/3 frequency reuse, while maintaining a stringent requirement of 2% packet loss probability for voice service.
