Optimal Power Allocation and AI Receiver Design for Superimposed DMRS and Data Transmission
Sha Hu, Zhongwang Fu
In this paper, we consider transmissions with superimposed (SI) demodulation-reference-symbol (DMRS) and data in orthogonal frequency-division multiplexing (OFDM) based multiple-in…

An Identity of Hankel Matrices Generated from the Moments of Gaussian Distribution
Sha Hu
In this letter, we proved a matrix identity of Hankel matrices that seems unrevealed before, generated from the moments of Gaussian distributions. In particular, we derived the Cho…
