Covariance Regularization for Probabilistic Linear Discriminant Analysis
Zhiyuan Peng, Mingjie Shao, Xuanji He +4
Probabilistic linear discriminant analysis (PLDA) is commonly used in speaker verification systems to score the similarity of speaker embeddings. Recent studies improved the perfor…
Divide and Conquer: One-Bit MIMO-OFDM Detection by Inexact Expectation Maximization
Mingjie Shao, Wing-Kin Ma
Adopting one-bit analog-to-digital convertors (ADCs) for massive multiple-input multiple-output (MIMO) implementations has great potential in reducing the hardware cost and power c…
One-Bit Symbol-Level Precoding for MU-MISO Downlink with Intelligent Reflecting Surface
Silei Wang, Qiang Li, Mingjie Shao
This paper considers symbol-level precoding (SLP) for multiuser multi-input single-output (MISO) downlink transmission with the aid of intelligent reflecting surface (IRS). Specifi…
Binary MIMO Detection via Homotopy Optimization and Its Deep Adaptation
Mingjie Shao, Wing-Kin Ma
In this paper we consider maximum-likelihood (ML) MIMO detection under one-bit quantized observations and binary symbol constellations. This problem is motivated by the recent inte…
Minimum Symbol-Error Probability Symbol-Level Precoding with Intelligent Reflecting Surface
Mingjie Shao, Qiang Li, Wing-Kin Ma
Recently, the use of intelligent reflecting surface (IRS) has gained considerable attention in wireless communications. By intelligently adjusting the passive reflection angle, IRS…
One-Bit Sigma-Delta MIMO Precoding
Mingjie Shao, Wing-Kin Ma, Qiang Li +1
Coarsely quantized MIMO signalling methods have gained popularity in the recent developments of massive MIMO as they open up opportunities for massive MIMO implementation using che…
