Orthogonal frequency division multiplexing (OFDM) has been widely adopted in modern
wireless communication systems due to its robustness against the frequency selectivity of …

The message-passing approach to model-based signal processing is developed with a
focus on Gaussian message passing in linear state-space models, which includes recursive …

We propose an iterative channel estimation algorithm based on the least square estimation
(LSE) and sparse message passing (SMP) algorithm for the millimeter wave (mmWave) …

This paper presents a practical low-density parity-check (LDPC) coded OFDM system
designed for the underwater acoustic channel with its attendant sparse multipath channel …

Many important schemes in signal processing and communications, ranging from the BCJR
algorithm to the Kalman filter, are instances of factor graph methods. This family of …

This paper deals with low-complexity joint channel estimation and decoding for faster-than-
Nyquist (FTN) signaling over frequency selective fading channels. The inter-symbol …

In this paper, we propose a new inference algorithm, suitable for distributed processing over
wireless networks. The algorithm, called uniformly reweighted belief propagation (URW-BP) …

We propose a block-by-block iterative receiver for underwater MIMO-OFDM that couples
channel estimation with multiple-input multiple-output (MIMO) detection and low-density …

This letter addresses the problem of signal detection in flat-fading channels. In this context,
receivers based on the expectation propagation framework appear to be very promising …

Channel uncertainty and co-channel interference are two major challenges in the design of
wireless systems such as future generation cellular networks. This paper studies receiver …
