论文摘要
随着物联网的迅速扩展，无线介质通过大量简单发射器的有效共享变得至关重要。基于调度的解决方案对于此设置效率低下，在这种情况下，小型数据单元是由大多数时候闲置的终端偶尔广播的。现代的随机访问已经接受了挑战，并提供了基于复制数据包并利用接收器的连续干扰取消（SIC）的合适的插槽同步和异步多访问解决方案。在这项工作中，我们专注于异步现代随机访问。具体而言，我们得出了所谓的误差地板区域中不规则重复ALOHA（IRA）性能的分析近似。数值结果表明，在各种情况下，派生的近似值的紧密度。
With the rapid expansion of the Internet of Things, the efficient sharing of the wireless medium by a large amount of simple transmitters is becoming essential. Scheduling-based solutions are inefficient for this setting, where small data units are broadcast sporadically by terminals that most of the time are idle. Modern random access has embraced the challenge and provides suitable slot-synchronous and asynchronous multiple access solutions based on replicating the packets and exploiting successive interference cancellation (SIC) at the receiver. In this work, we focus on asynchronous modern random access. Specifically, we derive an analytical approximation of the performance of irregular repetition ALOHA (IRA) in the so-called error floor region. Numerical results show the tightness of the derived approximation under various scenarios.
