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…
Equivalence of Serial and Parallel A-Posteriori Probabilities in the Decoding of DAB Systems
Andrea Di Giusto, Wim van Houtum, Alberto Ravagnani +1
Motivated by applications to digital audio broadcasting (DAB) systems, we study the a-posteriori probabilities (APPs) of the coded and information bits of the serial concatenation…
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…
