Quasisynchronous LoRa for LEO nanosatellite communications
(Institute of Electrical and Electronics Engineers Inc., 2023)
Perfect synchronization in LoRa communications between Low Earth Orbit (LEO) satellites and ground base stations is still challenging, despite the potential use of atomic clocks in LEO satellites, which offer high precision. ...
Network-independent and user-controlled RIS: An experimental perspective
(IEEE Computer Society, 2023)
The march towards 6G is accelerating and future wireless network architectures require enhanced performance along with significant coverage especially, to combat impairments on account of the wireless channel. Reconfigurable ...
Sequency index modulation: A novel index modulation for delay-sequency domain waveforms
(Institute of Electrical and Electronics Engineers Inc., 2023)
In this letter, the sequency domain is introduced as a novel resource to propose a new index modulation, which is named sequency index modulation (SeIM). In SeIM, information bits are implicitly conveyed through the indices ...
Error performance enhancement and complexity reduction in OFDM systems via coordinate interleaving under practical impairments
(Turkiye Klinikleri, 2024)
In this work, subcarrier coordinate interleaving (CI) is implemented to orthogonal frequency division multiplexing (OFDM) systems with the aim of both enhancing the error performance and reducing the implementation complexity. ...
