Precoded Non-Orthogonal Frequency Division Multiplexing with Subcarrier Index Modulation
Prakash Chaki, Takumi Ishihara, Shinya Sugiura
In this paper, we propose a novel precoded non-orthogonal frequency division multiplexing (NOFDM) with subcarrier index modulation (SIM) to increase spectral efficiency for multica…
Power-Domain-Multiplexed Precoded Faster-Than-Nyquist Signaling for NOMA Downlink
Prakash Chaki, Shinya Sugiura
In this paper, we propose a novel precoded faster-than-Nyquist (FTN) signaling scheme with power-domain-multiplexing in non-orthogonal multiple access (NOMA) downlink for tapping t…
Delay-Doppler-Domain Channel Estimation and Reduced-Complexity Detection of Faster-than-Nyquist Signaling Aided OTFS
Zekun Hong, Shinya Sugiura, Chao Xu +1
We conceive a novel channel estimation and data detection scheme for OTFS-modulated faster-than-Nyquist (FTN) transmission over doubly selective fading channels, aiming for enhanci…
Faster-than-Nyquist Signaling for Next-Generation Wireless: Principles, Applications, and Challenges
Shuangyang Li, Melda Yuksel, Tongyang Xu +4
Future wireless networks are expected to deliver ultra-high throughput for supporting emerging applications. In such scenarios, conventional Nyquist signaling may falter. As a reme…
