Rethinking: Deep-learning-based Demodulation and Decoding
Boxiang He, Zitao Wu, Fanggang Wang
In this paper, we focus on the demodulation/decoding of the complex modulations/codes that approach the Shannon capacity. Theoretically, the maximum likelihood (ML) algorithm can a…
Reconfigurable-intelligent-surface-assisted Downlink Transmission Design via Bayesian Optimization
Dong Wang, Xiaodong Wang, Fanggang Wang
This paper investigates the transmission design in the reconfigurable-intelligent-surface (RIS)-assisted downlink system. The channel state information (CSI) is usually difficult t…
Blind Channel Estimation and Data Detection with Unknown Modulation and Coding Scheme
Yu Liu, Fanggang Wang
This paper investigates a complete blind receiver approach in an unknown multipath fading channel, which has multiple tasks including blind channel estimation, noise power estimati…
Spatial Coded Modulation
Junshan Luo, Fanggang Wang, Shilian Wang
In this paper, we propose a spatial coded modulation (SCM) scheme, which improves the accuracy of the active antenna detection by coding over the transmit antennas. Specifically, t…
Jamming-Aided Secure Communication in Massive MIMO Rician Channels
Jue Wang, Jemin Lee, Fanggang Wang +1
In this paper, we investigate the artificial noise-aided jamming design for a transmitter equipped with large antenna array in Rician fading channels. We figure out that when the n…
Wireless MIMO Switching: Weighted Sum Mean Square Error and Sum Rate Optimization
Fanggang Wang, Xiaojun Yuan, Soung Chang Liew +1
This paper addresses joint transceiver and relay design for a wireless multiple-input-multiple-output (MIMO) switching scheme that enables data exchange among multiple users. Here,…
Wireless MIMO Switching with Zero-forcing Relaying and Network-coded Relaying
Fanggang Wang, Soung Chang Liew, Dongning Guo
A wireless relay with multiple antennas is called a multiple-input-multiple-output (MIMO) switch if it maps its input links to its output links using "precode-and-forward." Namely,…
Wireless MIMO Switching with Network Coding
Fanggang Wang, Soung Chang Liew
In a generic switching problem, a switching pattern consists of a one-to-one mapping from a set of inputs to a set of outputs (i.e., a permutation). We propose and investigate a wi…

Low Complexity Kolmogorov-Smirnov Modulation Classification
Fanggang Wang, Rongtao Xu, Zhangdui Zhong
Kolmogorov-Smirnov (K-S) test-a non-parametric method to measure the goodness of fit, is applied for automatic modulation classification (AMC) in this paper. The basic procedure in…
Coherent Optical DFT-Spread OFDM
Fanggang Wang, Xiaodong Wang
We consider application of the discrete Fourier transform-spread orthogonal frequency-division multiplexing (DFT-spread OFDM) technique to high-speed fiber optic communications. Th…
