Advanced Codebook Design for SCMA-aided NTNs With Randomly Distributed Users
Tianyang Hu, Qu Luo, Lixia Xiao +3
In this letter, a novel class of sparse codebooks is proposed for sparse code multiple access (SCMA) aided non-terrestrial networks (NTN) with randomly distributed users characteri…
Amplitude-Domain Reflection Modulation for Active RIS-Assisted Wireless Communications
Jing Zhu, Qu, Luo +5
In this paper, we propose a novel active reconfigurable intelligent surface (RIS)-assisted amplitude-domain reflection modulation (ADRM) transmission scheme, termed as ARIS-ADRM. T…
Channel Estimation for AFDM With Superimposed Pilots
Kai Zheng, Miaowen Wen, Tianqi Mao +2
The recent proposed affine frequency division multiplexing (AFDM) employing a multi-chirp waveform has shown its reliability and robustness in doubly selective fading channels. In…
