Power control for wireless packet packet with application to EDGE system |
摘要 |
A Kalman-filter power control method is applied to a packet voice service in a wireless network based on interference tracking and predictions. An Enhanced Data for GSM Evolution (EDGE) system is used as an illustrative platform for the invention. 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. For allocated spectrum of 1.8, 3.6 and 5.4 MHz, the 1/3 reuse with the Kalman power control can yield 102.5%, 49.5% and 32.5% improvement in spectral efficiency over the 3/9 reuse, respectively.
