The LDACS-1 and LDACS-2 Physical Layer implementations utilize MATLAB for simulating communication mechanisms tailored for the L-Band Digital Aeronautical Communication System. These versions, LDACS-1 and LDACS-2, support different modulation schemes: LDACS-1 employs the Orthogonal Frequency Division Multiplexing (OFDM) technique, providing support for Frequency Division Duplex (FDD) topologies, while LDACS-2 is based on GSM technology and supports Time Division Duplex (TDD) configurations. The project's objective is to facilitate robust communication between Aircraft Stations and Ground Stations, referred to as reverse and forward links respectively. This dual-mode physical layer helps improve data transmission efficiency and ensures seamless integration with existing aeronautical communication systems. Ideal for aerospace communication frameworks, the LDACS systems are designed to enhance communication reliability amidst the challenges of high-speed aerial environments.
