Abstract Satellite communications, driven by increasing complexity and demand, require innovative solutions for both physical and logical system layers. This work focuses on optimizing delta modulation within a reconfigurable electronic architecture to enhance hardware performance in satellite applications. Delta modulation, a widely used sampling and quantization technique in wireless applications, is examined in the context of analog-to-digital conversion, a critical stage in satellite telemetry transmission. Implementing this technique in a reconfigurable architecture offers several advantages: optimization of power consumption, facilitating integration into more compact systems and reducing the energy impact on satellites; miniaturization, enabling the creation of smaller, more efficient devices; flexibility, adapting to various operational requirements and improving system versatility; and improved transmission quality, providing more reliable and effective communication. This study highlights delta modulation’s potential to optimize hardware and efficiency in satellite communications applications.
