heal.abstract	Satellite communication networks play a significant role to worldwide telecommunication infrastructure providing direct-to-mobile user satellite services. Quality of Service requirements should be taken into account in the satellite power allocation schemes that follow the channel variations. Employing a shadowed Rician model for land mobile satellite communications and an adaptive modulation scheme, closed form expressions are derived for the optimal power allocation and the effective capacity. The effective capacity of the system under specific Quality of Service constraints is maximized. Finally, the impact of the elevation angle on the power allocation and the effective capacity is investigated. © 2006 IEEE.	en
