Abstract
Contention resolution diversity slotted ALOHA (CRDSA) with packet repetition and iterative interference cancellation (IIC) has been proven that achieves \(48\%\) improvement in terms of throughput than pure slotted ALOHA which merely has a theoretical throughput upper bound of 0.36. So far, optimizations of such random access scheme have been proposed in the literature called irregular repetition slotted ALOHA (IRSA) and coded slotted ALOHA (CSA) which both targeted the collision channel model. In this paper, the environment of LEO satellite communication and capture effect at the satellite receiver are considered. Meanwhile, due to the inherent propagation feature of LEO satellite, capture effect can be enhanced through separating LEO footprint into districts. Under a setting of finite frame length, this separating scheme is analyzed via Monte Carlo simulation combining with optimized power control. Numerical results are provided, which prove the stability of proposed scheme when channel load exceeding 1.
