Overview (resum en anglès):
This document outlines the fundamental concepts of the physical layer in the 5G New Radio telecommunication protocol. It focuses particularly on the implementation of signal processing algorithms used in Downlink transmission, specifically for the data, broadcast, and control channels. To carry out the implementation and testing of these algorithms, the ALOE framework will be used. ALOE is a Linux-based modular system designed to both simulations and real-time executions, where the signal can be propagated as if in a real transmission scenario, which makes it a suitable tool for research and prototyping in communication systems.
It is important to highlight that this project exclusively addresses the Downlink portion of the communication system. It does not cover Uplink processes, nor does it consider inter-satellite communications or handover mechanisms between satellites. The primary focus is on ensuring that the signal can be successfully transmitted from a satellite directly to end-user mobile devices on Earth.
The system will be designed and dimensioned to allow for satellite-to-device communication, with an emphasis on providing consistent and reliable coverage over the Iberian Peninsula. The target is to achieve at least 99.5% service availability over time using the minimum number of satellites necessary, thereby minimizing costs. To achieve this, an optimized satellite constellation will be proposed based on coverage analysis and propagation simulations.
Additionally, a preliminary design will be presented, which takes into account all the technical and operational requirements for a satellite to remain functional in orbit for a period of five years, delivering uninterrupted service during that time. This includes considerations such as power management, thermal control, radiation tolerance shielding¿
After implementing the signal processing algorithms and testing them within atmospheric propagation simulation environments, it has been confirmed that the system meets the performance requirements. Specifically, the configuration designed for the most robust propagation conditions guarantees 99.5% service uptime.
