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…
