Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 This study proposes an iterative, joint channel estimation, equalization, and data detection method in the presence of high mobility for a multicarrier downlink system that communicates over rapidly time‐varying channels. The proposed method uses a basis expansion method (BEM) which has low computational complexity and helps to reduce the number of ...

A PAPR correction scheme for LoRa self‐jamming waveforms
IET Communications, Volume 18, Issue 19, Page 1588-1603, December 2024.A self‐jamming scheme of LoRa waveforms enabling secure transmissions is recently proposed in literature, which performs well in simulations. However, experiments on SDR equipment immediately showed that a transmission is impossible due to PAPR introduced by the waveform modification.
