In this paper we explore the performance of a selective decision directed channel estimation
(CE) method for underwater acoustic (UWA) orthogonal frequency division multiplexing …

Orthogonal Time Frequency Space (OTFS) modulation is a recently proposed modulation
pattern aiming to overcome problems in high mobility scenarios. Parameter learning …

Deep learning (DL) has emerged as an effective tool for channel estimation in wireless
communication systems, especially under some imperfect environments. However, even …

The last few decades have seen an exponential increase in the demand for wireless
connectivity. A channel estimator is a successful strategy for transferring data over wireless …

(OFDM) systems need accurate channel estimation in order to compensate for the
distortions caused by propagation through the dispersive channel. This work compares two …

Channel estimation is critical for coherent detection in OFDM systems. In pilot symbol aided
channel estimation methods, the LS channel estimation can be viewed as a noisy …

The standardization process of the fifth generation (5G) wireless communications has
recently been accelerated and the first commercial 5G services would be provided as early …

In this work, a Bayesian framework for OFDM channel estimation is proposed. Using the
maximum entropy principle to exploit prior system information at the receiver, we …

Time-domain wireless channels are generally modeled by Tapped Delay Line (TDL) model
and its variants. These models are not effective for channel representation and estimation …

This paper presents a low-complexity/low-latency algorithm for estimating and tracking time-
varying fading channels in Orthogonal Frequency Division Multiplexing (OFDM) systems …
