Simulated Implementation of L-Band Digital Aeronautical Communication System (LDACS) Based Communication Navigation and Surveillance Network for Pakistani Airspace

EasyChair Preprint 10309

Abstract

The L Band Digital Aeronautical Communication System (LDACS) is a new generation of air-ground communication systems designed to meet the increasing demand for air traffic data transmission. It is based on cellular concept. The system has been under trial in Europe. This paper presents a detailed architecture and simulated performance validation of LDACS in Northern Airspace of Pakistan. The focus is on the system's ability to provide high-speed data transmission, improved coverage, and increased spectrum efficiency while ensuring compatibility with existing communication systems. The LDACS system is intended to provide a reliable, secure, and cost-effective solution for air-ground communication in the L band frequency range. The paper primarily verifies performance verification of Communication and Navigation features. The verification of communication comprises coverage, reliability in terms of BER, Cell sizes for frequency reuse. The modulation scheme is Orthogonal Frequency Division Multiplexing (OFDM) where sub-carriers are to be adjusted in available pockets “L” band. The Navigation feature is tested in terms of flight path accuracy and Required Navigation Performance (RNP) category is determined. Simulations are carried out using GNU radio, and MATLAB.
