| Description: | We investigate a downlink channel assignment scheme for multipoint communications and we propose a new simulcast-based dynamic channel assignment policy for both unicast and multicast connections in LEO satellite networks. In order to reduce co-channel interference power and to avoid intersymbol interference problem, our policy is combined with a power control algorithm. Performance evaluations show that our policy compared to other policies achieve bandwidth optimization and improves the quality of service since it reduces call blocking probabilities for both unicast and multicast connections. |
