The numbers of multimedia applications and their users increase with each passing day.
Different multi-carrier systems have been developed along with varying techniques of space …

OFDM is a powerful modulation technique that efficiently transmits high-speed digital data
over frequency-selective fading channels. It divides the signal into multiple subcarriers, each …

Automatic modulation classification (AMC) aims to identify the modulation type of received
signals, playing a crucial role in ensuring secure dynamic spectrum access in the Cognitive …

Blindly decoding a signal requires estimating its unknown transmit parameters,
compensating for the wireless channel impairments, and identifying the modulation type …

Automatic modulation classification (AMC) for overlapped sources plays an important role in
spectrum monitoring and signal interception. In this paper, we propose a feature-based AMC …

We investigate practical aspects of a recently introduced blind (noncoherent) communication
scheme, called modulation on conjugate-reciprocal zeros (MOCZ). MOCZ is suitable for a …

We consider a multihop distributed uplink reception system in which K users transmit
independent messages to one data center of N r≥ K receive antennas, with the aid of …

Modulation classification is one of the key tasks for communications systems monitoring,
management, and control for addressing technical issues, including spectrum awareness …

In this paper, we propose an iterative soft channel estimation and data detection algorithm
based on a factor graph. Channel coefficients as well as data symbols are treated as …

In partial label (PL) learning, each instance corresponds to a set of candidate labels, among
which only one is valid. The objective of PL learning is to obtain a multi-class classifier from …
