Chirp css

WebWith the proliferation of Internet-of-Things (IoT), the chirp spread spectrum (CSS) technique is re-emerging for communications. Although CSS can offer high processing gain, its poor spectral efficiency and the lack of orthogonality among different chirps tend to limit its potential. In this paper, we derive the condition to orthogonally multiplex an arbitrary … WebAug 22, 2024 · This study delves deeply into the waveform design of the CSS-based PHY layer alternatives to LoRa, and proposes coherent/non-coherent detection mechanisms for specific schemes that have not been previously documented in the literature.
