摘要

固定、便携式和移动终端使用随机存取(RA)来传输数据或请求频谱效率更高的专用资源。本文介绍了一种新的多址方案——a - SCMA，它具有不同步传输和低功耗的特点，特别适用于卫星或地面应用中的小型机对机通信。多载波版本可以在大且可变的数据包大小下运行，而不会降低吞吐量或造成大延迟。

Asynchronous Scrambled Coded Multiple Access (A-SCMA) - A New High Efficiency Random Access Method

Fixed, portable and mobile terminals use Random Access (RA) to transfer data or request more spectrally efficient dedicated resources. This paper describes a new multiple access scheme, A- SCMA, that operates with unsynchronized transmission and low power, making it particularly suitable to small machine-to-machine communications in satellite or terrestrial applications. A multicarrier version operates with large and variable packet sizes without reduced throughput or large delays.
