改善LoRa-like网络上行链路的串行干扰消除
Serial Interference Cancellation for Improving uplink in LoRa-like Networks
摘要：
在本文中，我们提出了一种新的接收器设计，它显著提高了物联网网络（如LoRa）的性能，即，具有线性调频扩频调制。所提出的接收机能够解调多个用户同时发送在同一频率信道上具有相同的扩频因子。从非正交多址接入的角度来看，它基于功率域并使用串行干扰消除。仿真结果表明，接收器允许在网络中的连接设备的数量显着增加。
英文摘要：
In this paper, we present a new receiver design, which significantly improves performance in the Internet of Things networks such as LoRa, i.e., having a chirp spread spectrum modulation. The proposed receiver is able to demodulate multiple users simultaneously transmitted over the same frequency channel with the same spreading factor. From a non-orthogonal multiple access point of view, it is based on the power domain and uses serial interference cancellation. Simulation results show that the receiver allows a significant increase in the number of connected devices in the network.
