Abstract
The goal of this paper is to propose a MAC (Medium Access Control) layer to the LEO (Low Earth Orbiting) satellite channel for voice users in order to use efficiently the radio channel bandwidth. This protocol is based on CDMA/PRMA one and adapted to LEO systems. It uses CDMA (Code Division Multiple Access) technique combined with PRMA (Packet Reservation Multiple Access) protocol. A CAC (Connection Admission Control) function that maximizes the number of accepted users with predefined guaranteed QoS (Quality of Service) is then introduced. Furthermore, users traffic control methods are proposed and studied by simulation. The channel parameters are chosen in order to maximize the resource utilization by the proposed protocol.
