Abstract	Considering the advantage of interleave-division multiple-access (IDMA) technique and the technical bottlenecks in the existing satellite systems, IDMA is introduced into satellite communication networks. To maximize the resource utilization in IDMA-based multi-beam satellite systems, a new power allocation scheme based on SINR evolution technique is proposed. To further validate the IDMA into satellite systems, an effective call admission control (CAC) based on the proposed power allocation scheme is developed. Analysis and simulation results show that, compared to the traditional CAC scheme, IDMA under the proposed scheme can not only provide better QoS, in terms of the blocking/dropping probability as well as outage probability, but also improve the power efficiency and normalized throughput, especially in heavy load conditions.
