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…

Symbiotic Cognitive Relaying with mobile Secondary nodes in Cognitive Radio Networks
Prakash Chaki, Gouri Nawathe, Aaqib Patel +2
In a Symbiotic Cognitive Relaying (SCR) scenario, the Secondary users(SU) nodes can act as multihop relays to assist the communication between Primary User(PU) nodes in the case of…
