An important modulation technique for Internet of Things (IoT) is the one proposed by the low power long range (LoRa) alliance. In this paper, we analyze the <inline-formula> <tex-math notation="LaTeX">$M$ </tex-math></inline-formula>-ary LoRa modulation in the time and frequency domains. First, we provide the signal description in the time domain, and show that LoRa is a memoryless continuous phase modulation. The cross-correlation between the transmitted waveforms is determined, proving that… Expand
On the Error Rate of the LoRa Modulation With Interference
TLDR
This work examines the performance of LoRa in the presence of both additive white Gaussian noise and interference from another LoRa user and derives low-complexity approximate formulas that can significantly reduce the complexity of computing the symbol and frame error rates compared to the complete expression.

Slope-Shift Keying LoRa-Based Modulation
TLDR
This article uses a linearly varying-frequency down chirp and its cyclic shifts to generate the second set of orthonormal basis functions in the proposed scheme, named slope-shift-keying LoRa (SSK-LoRa) modulation, which is shown to outperform the state-of-the-art LoRa-based modulation schemes.

TLDR
This paper presents a new modulation, called DLoRa, similar in principle to the conventional LoRa modulation and compatible with it in terms of bandwidth and numerology, and shows that it is possible to double the number of channels by simultaneously using LoRa and DLora. Expand
The LoRa Modulation Over Rapidly-Varying Channels: Are the Higher Spreading Factors Necessarily More Robust?
TLDR
The primary observation is that over rapidly-varying channels, the robustness benefits of the larger spreading factors tend to disappear as the payload size grows, highlighting the need to consider channel characteristics and payload sizes in allocating the spreading factor for reliable and energy-efficient LoRa communications.
