Future Mars landing missions will require the capability of precise landing at certain sites for
specific scientific interests to gather more valuable scientific information. Autonomous …

Carrier synchronization is a fundamental stage in the receiver side of any communication or
positioning system. Traditional carrier phase tracking techniques are based on well-known …

A Multi-Constellation Software-Defined Receiver (MC-SDR) is designed and implemented to
extract the Doppler measurements of Low Earth Orbit (LEO) satellite's downlink signals …

A framework for positioning with low Earth orbit (LEO) satellite signals is proposed. The
framework employs an extend Kalman filter (EKF) to estimate a receiver's position using …

Cognitive radios have become a key research area in communications over the past few
years. Automatic modulation classification (AMC) is an important component that improves …

In this paper, we propose an algorithm for the classification of digital amplitude-phase
modulated signals in flat fading channels with non-Gaussian noise. The additive noise is …

The promise of broadband low-Earth orbit (LEO) satellite signals for positioning, navigation,
and timing (PNT) has been demonstrated in the past decade [1–7]. While some LEO-based …

Availability of higher capacity for both uplinks and downlinks is expected in the future deep-
space missions on Mars, thus enabling a large range of services that could eventually …

In this paper, we focus on amplitude-phase modulations and propose a modulation
classification framework based on centralized data fusion using multiple radios and the …

Space exploration has been on the rise since the 1960s and Mars plays a significant role in
the history of space exploration. As the amount of data collected from science instruments …
