论文摘要
在本文中，我们提出了一种称为Dlora的新调制，原则上类似于传统的Lora调制，并且在带宽和命理学方面与其兼容。 Dlora偏离了常规的Lora调制，因为它使用了chir频中的瞬时频率，而不是增加lora lora调制的速度。此外，我们描述了一种软件环境，以准确评估使用不同扩散因子时洛拉和Dlora创建的不同虚拟通道的“隔离”。我们的结果与传统LORA调制的文献中存在的结果一致，并表明可以通过同时使用Lora和Dlora将通道数量加倍。可用的子渠道数量较高（双重）是改善基于洛拉网络的网络级别性能的关键。
In this paper we present a new modulation, called DLoRa, similar in principle to the conventional LoRa modulation and compatible with it in terms of bandwidth and numerology. DLoRa departs from the conventional LoRa modulation as it is using a decreasing instantaneous frequency in the chirps instead of an increasing one as for the conventional LoRa modulation. Furthermore we describe a software environment to accurately evaluate the "isolation" of the different virtual channels created both by LoRa and DLoRa when using different Spreading Factors. Our results are in agreement with the ones present in literature for the conventional LoRa modulation and show that it is possible to double the number of channels by using simultaneously LoRa and DLora. The higher (double) number of subchannels available is the key to improve the network level performance of LoRa based networks.
