Distributed Expectation Propagation Detection for Cell-Free Massive MIMO
Hengtao He, Hanqing Wang, Xianghao Yu +3
In cell-free massive MIMO networks, an efficient distributed detection algorithm is of significant importance. In this paper, we propose a distributed expectation propagation (EP)…
Dynamic Metasurface Antennas for MIMO-OFDM Receivers with Bit-Limited ADCs
Hanqing Wang, Nir Shlezinger, Yonina C. Eldar +4
The combination of orthogonal frequency modulation (OFDM) and multiple-input multiple-output (MIMO) systems plays an important role in modern communication systems. In order to mee…
Expectation Propagation Detector for Extra-Large Scale Massive MIMO
Hanqing Wang, Alva Kosasih, Chao-Kai Wen +2
The order-of-magnitude increase in the dimension of antenna arrays, which forms extra-large-scale massive multiple-input-multiple-output (MIMO) systems, enables substantial improve…
Reliable OFDM Receiver with Ultra-Low Resolution ADC
Hanqing Wang, Wan-Ting Shih, Chao-Kai Wen +1
The use of low-resolution analog-to-digital converters (ADCs) can significantly reduce power consumption and hardware cost. However, their resulting severe nonlinear distortion mak…
Deep Learning for Wireless Physical Layer: Opportunities and Challenges
Tianqi Wang, Chao-Kai Wen, Hanqing Wang +3
Machine learning (ML) has been widely applied to the upper layers of wireless communication systems for various purposes, such as deployment of cognitive radio and communication ne…
Bayesian Optimal Data Detector for mmWave OFDM System with Low-Resolution ADC
Hanqing Wang, Chao-Kai Wen, Shi Jin
Orthogonal frequency division multiplexing (OFDM) has been widely used in communication systems operating in the millimeter wave (mmWave) band to combat frequency-selective fading…
