Time Sharing Policy in Wireless Networks for Variable Rate Transmission
— For most of wireless services with variable rate transmission, both average rate and rate oscillation are important performance metrics. One often needs to decide how much rate...

QoS-Driven Power Allocation Over Parallel Fading Channels With Imperfect Channel Estimations in Wireless Networks
— We propose the quality-of-service (QoS) driven power allocation schemes for parallel fading channels when considering imperfect channel estimations. In particular, the parallel...
