Abstract: In non-coherent chaotic communications, traditional code-index-modulation-aided differential chaos shift keying (DCSK) schemes face limited gains in bit-error-rate (BER) performance, despite incurring substantial time-frequency resources. To address this challenge, we propose a new reconfigurable intelligent surface… read more here.

DOI: 10.1109/lwc.2023.3246132
Abstract: This letter proposes a method to approximate LoRa performance over heavy multipath channels. Firstly, the multipath time delay and LoRa signal duration are combined to analyze the path overlapping interference quantitatively. Then simple BER approximations… read more here.
