In this paper, we present a realistic use case in order to investigate the feasibility of a secondary service transmission over an existent satellite infrastructure. By introducing the overlay cognitive radio paradigm towards satellite communications, we compute a theoretical achievable data rate greater than 16 kbps for the secondary service, which is suitable for most M2M applications. Using simulation results, we show that this can be achieved while preserving the primary service performance. In addition, a system design framework is discussed in order to dimension such systems.

关于在现有卫星基础设施上进行二次业务传输的可行性：设计和分析

在本文中，我们提出了一个实际的用例，以研究通过现有卫星基础设施进行二次服务传输的可行性。通过将覆盖认知无线电范例引入卫星通信，我们为辅助服务计算出理论上可达到的大于16 kbps的数据速率，适用于大多数M2M应用。使用仿真结果，我们表明可以在保留主要服务性能的同时实现这一目标。另外，讨论了系统设计框架以便确定此类系统的尺寸。
