Kurzfassung englisch:
The L-Band Digital Aeronautical CommunicationSystem (LDACS) is a new aeronautical communication standardbetween an aircraft and a ground station, which provides highdata throughput with different modulation and channel codingschemes for reliable transmission. Conducted measurements ofthe LDACS receiver (RX) prototype have shown that the BitError Rate (BER) severely suffers for higher modulation schemes,while for lower modulation schemes, the results perfectly matchwith the stated ones in the LDACS standard. This paper evaluatesthe BER performance for all define link types, modulationschemes, and channel types by simulations. As a matter of fact,some modulation and coding schemes define in the LDACSstandard show a strong degeneration of the BER for somechannel types. Therefore, the different channel types are analyzedin this paper, and the pilot grid spacing is examined according to the underlying channel realizations regarding the phase variations of the channel by adjacent orthogonal frequency-division multiplexing (OFDM) symbols.
