The use of aeronautical vehicles and consequently their communication traffic are growing rapidly, and soon there will be demands for channels with larger bandwidths. The L-band digital aeronautical communication system (L-DACS1) was proposed by EUROCONTROL as an OFDM based multicarrier communication system candidate, with channels "inlayed" between distance measuring equipment (DME) channels. We previously proposed a similar communication system based on the Filter Bank Multicarrier (FBMC) technique, which has some significant advantages over L-DACS1. In this paper several diversity and multiple antenna techniques for L-DACS1 and FBMC AG communication systems are investigated. The correlation coefficient between realistic receiver aircraft antenna channels is computed, and using these realistic channels-based upon NASA channel measurements-link performance is simulated to generate BER results. Simulation results show the advantages of using multiple antennas at the receiver, and the antenna separations required (as a function of link distance) to attain nearly uncorrelated channels for two suburban areas. MIMO performance gains are quantified and show significant improvement over single-antenna systems, especially for higher order modulations.
