Low-Complexity Tone Injection via Candidate Ranking for PAPR Reduction in OFDM and AFDM Systems
Yupeng Zheng, Ang Li, Jinfei Wang +2
Tone injection (TI) is a promising distortionless PAPR reduction technique that incurs no spectral efficiency loss. However, state-of-the-art TI schemes based on random candidate g…
Block-Weighted Lasso for Joint Optimization of Memory Depth and Kernels in Wideband DPD
Jinfei Wang, Yi Ma, Fei Tong +1
The optimizations of both memory depth and kernel functions are critical for wideband digital pre-distortion (DPD). However, the memory depth is usually determined via exhaustive s…
Exploiting Non-uniform Quantization for Enhanced ILC in Wideband Digital Pre-distortion
Jinfei Wang, Yi Ma, Fei Tong +1
In this paper, it is identified that lowering the reference level at the vector signal analyzer can significantly improve the performance of iterative learning control (ILC). We pr…
On Chernoff Lower-Bound of Outage Threshold for Non-Central -Distributed Beamforming Gain in URLLC Systems
Jinfei Wang, Yi Ma, Rahim Tafazolli +1
The cumulative distribution function (CDF) of a non-central -distributed random variable (RV) is often used when measuring the outage probability of communication systems. For…

Sherman-Morrison Regularization for ELAA Iterative Linear Precoding
Jinfei Wang, Yi Ma, Na Yi +1
The design of iterative linear precoding is recently challenged by extremely large aperture array (ELAA) systems, where conventional preconditioning techniques could hardly improve…
Constellation-Oriented Perturbation for Scalable-Complexity MIMO Nonlinear Precoding
Jinfei Wang, Yi Ma, Na Yi +2
In this paper, a novel nonlinear precoding (NLP) technique, namely constellation-oriented perturbation (COP), is proposed to tackle the scalability problem inherent in conventional…
Power Allocation for FDMA-URLLC Downlink with Random Channel Assignment
Jinfei Wang, Yi Ma, Na Yi +1
Concerning ultra-reliable low-latency communication (URLLC) for the downlink operating in the frequency-division multiple-access with random channel assignment, a lightweight power…
Network-ELAA Beamforming and Coverage Analysis for eMBB/URLLC in Spatially Non-Stationary Rician Channels
Jinfei Wang, Yi Ma, Na Yi +2
In vehicle-to-infrastructure (V2I) networks, a cluster of multi-antenna access points (APs) can collaboratively conduct transmitter beamforming to provide data services (e.g., eMBB…
Massive-MIMO MF Beamforming with or without Grouped STBC for Ultra-Reliable Single-Shot Transmission Using Aged CSIT
Jinfei Wang, Yi Ma, Na Yi +2
The technology of using massive transmit-antennas to enable ultra-reliable single-shot transmission (URSST) is challenged by the transmitter-side channel knowledge (i.e., CSIT) imp…
