In this paper, we propose a new code-aided (CA) timing recovery algorithm for various linear
constant modulus constellations based on the Maximum Likelihood (ML) estimator. The first …

Orthogonal Chirp Division Multiplexing (OCDM) is a promising multi-carrier modulation for
Underwater Acoustic (UWA) systems, as several low complexity OCDM receivers capable of …

The underwater acoustic channel is time-varying with a particularly limited bandwidth. This
makes reliable communications difficult to achieve and limits the information rate. The …

In this paper, we propose a maximum likelihood based Code-Aided (CA) timing recovery
algorithm for square-QAM modulated signals. We also theoretically derive the analytical …

In this paper, we propose a time synchronization algorithm for the WBAN frame structure
specified by the IEEE 802.15. 6 standard. This algorithm is based on a non coherent timing …

Traditional methods for ensuring secure communications typically rely on encryption, which
necessitates some form of coordination between the transmitter and the receiver. The Direct …

In this paper, we review advanced synchronization techniques for the internet of things. Our
study can be directly applied to the single-carrier IEEE 802.15. 4 and IEEE 802.15. 6 …

This paper presents a fully adaptive Minimum Mean Square Error (MMSE) iterative
equalization with a joint phase estimation, using various adaptive step-sizes scheme. To …

This paper proposes a novel equalization algorithm for underwater communication. It
performs iteratively adaptive equalization and channel decoding in order to reduce …

Jamming attacks can severely limit wireless networks availability and can cause serious
damage, in particular for tactical applications. Over the past decades, Direct-Sequence …
