Statistical Characterization and Block-EM Estimation of Frequency-Domain NSI for OFDM Systems in Bursty Impulsive Noise
Chin-Hung Chen, Wim van Houtum, Yan Wu +1
Impulsive noise (IN), characterized by its high power and non-Gaussian distribution, poses a critical challenge in modern orthogonal frequency-division multiplexing (OFDM) systems,…
Blind Turbo Demodulation for Differentially Encoded OFDM with 2D Trellis Decomposition
Chin-Hung Chen, Yan Wu, Wim van Houtum +1
Digital Audio Broadcasting (DAB)-like systems employ differentially encoded (DE) phase-shift keying (PSK) for transmission. While turbo-DE-PSK receivers offer substantial performan…
Phase-Aware Code-Aided EM Algorithm for Blind Channel Estimation in PSK-Modulated OFDM
Chin-Hung Chen, Ivana Nikoloska, Wim van Houtum +2
This paper presents a fully blind phase-aware expectation-maximization (EM) algorithm for OFDM systems with the phase-shift keying (PSK) modulation. We address the well-known local…
Physics-Aware Initialization Refinement in Code-Aided EM for Blind Channel Estimation
Chin-Hung Chen, Ivana Nikoloska, Wim van Houtum +2
This paper addresses the well-known local maximum problem of the expectation-maximization (EM) algorithm in blind intersymbol interference (ISI) channel estimation. This problem pr…
Robust Blind Channel Estimation for Bursty Impulsive Noise with a Constrained EM Approach
Chin-Hung Chen, Ivana Nikoloska, Wim van Houtum +3
Impulsive noise (IN) commonly generated by power devices can severely degrade the performance of high sensitivity wireless receivers. Accurate channel state information (CSI) knowl…
Modified Baum-Welch Algorithm for Joint Blind Channel Estimation and Turbo Equalization
Chin-Hung Chen, Boris Karanov, Ivana Nikoloska +3
Blind estimation of intersymbol interference channels based on the Baum-Welch (BW) algorithm, a specific implementation of the expectation-maximization (EM) algorithm for training…
Turbo Receiver Design for Differentially Encoded PSK in Bursty Impulsive Noise Channels
Chin-Hung Chen, Boris Karanov, Wim van Houtom +2
It has been recognized that the impulsive noise (IN) generated by power devices poses significant challenges to wireless receivers. In this paper, we comprehensively assess the ach…
On the Robustness of Deep Learning-aided Symbol Detectors to Varying Conditions and Imperfect Channel Knowledge
Chin-Hung Chen, Boris Karanov, Wim van Houtum +3
Recently, a data-driven Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm tailored to channels with intersymbol interference has been introduced. This so-called BCJRNet algorithm utilizes…
