SC-FDMA as a Delay-Doppler Domain Modulation Technique
Through mathematical and numerical analysis, it is confirmed that SC-FDMA is in fact a delay-Doppler domain multiplexing technique that can achieve the same performance gains as those of OTFS in time-varying wireless environments.
A Unified Framework for Pulse-Shaping on Delay-Doppler Plane
Delay-Doppler multiplexing has recently stirred a great deal of attention in research community.
Downlink Transmission in FBMC-based Massive MIMO with Co-located and Distributed Antennas
In practical scenarios, a perfect channel reciprocity may not hold due to radio chain mismatches in the uplink and downlink.
A Generalized Framework for Pulse-Shaping on Delay-Doppler Plane
The primary objective of this paper is to establish a generalized framework for pulse-shaping on the delay-Doppler plane.
Truncated Turbo Equalizer with SIC for OTFS
To evaluate the performance of our proposed truncated turbo equalizer with SIC (TTE-SIC), we set the minimum mean squared error (MMSE) equalizer without channel truncation as a benchmark.
Low-Complexity Reliability-Based Equalization and Detection for OTFS-NOMA
Motivated by this, in this paper we propose a low-complexity method for equalization and detection for OTFS-NOMA.
RIS Meets Aerodynamic HAPS: A Multi-objective Optimization Approach
In this paper, we propose a novel network architecture for integrating terrestrial and non-terrestrial networks (NTNs) to establish connection between terrestrial ground stations which are unconnected due to blockage.
Practical Synchronization for OTFS
Hence, in this paper, we propose a timing offset (TO) and carrier frequency offset (CFO) estimation for OTFS over a linear time-varying (LTV) channel, using a low PAPR pilot structure.
Low-Complexity Equalization and Detection for OTFS-NOMA
Our proposed method uses an iterative process where in each iteration, an equalizer based on the least-squares with QR factorization (LSQR) algorithm is followed by a novel reliability zone (RZ) detection scheme which estimates the reliable symbols of the users and then uses interference cancellation to remove MUI.
Downlink Precoding for FBMC-based Massive MIMO with Imperfect Channel Reciprocity
We theoretically analyze the performance of the proposed precoder in the presence of imperfect CSI and channel reciprocity calibration errors.
Joint CFO and Channel Estimation for RIS-aided Multi-user Massive MIMO Systems
This becomes more critical in RIS-aided communications, as even a small channel estimation error leads to a significant performance loss.
FBMC Receiver Design and Analysis for Medium and Large Scale Antenna Systems
In this paper, we design receivers for filter bank multicarrier-based (FBMC-based) massive MIMO considering practical aspects such as channel estimation and equalization.
Resource Allocation for Mixed Numerology NOMA
Non-orthogonal multiple access (NOMA) techniques can potentially be used to accommodate users with different numerologies while also gaining the performance benefits associated with NOMA.
Low-Complexity Joint CFO and Channel Estimation for RIS-aided OFDM Systems
Accurate channel estimation is essential for achieving the performance gains offered by reconfigurable intelligent surface (RIS)-aided wireless communications.
Spectral Domain Spline Graph Filter Bank
In this paper, we present a structure for two-channel spline graph filter bank with spectral sampling (SGFBSS) on arbitrary undirected graphs.
Evolving Intelligent Reflector Surface towards 6G for Public Health: Application in Airborne Virus Detection
While metasurface based intelligent reflecting surfaces (IRS) are an important emerging technology for future generations of wireless connectivity in its own right, the plans for the mass deployment of these surfaces motivate the question of their integration with other new and emerging technologies that would require mass proliferation.
