Paper Abstract

In this paper, we propose a frequency domain simulation structure for aeronautical wideband frequency-selective HF channel, which features ground-air wireless links. With appropriate channel parameters, the emulator can model the en-route scenarios of aircraft. The wideband frequency-selective channel consists of some parallel sub-channels in frequency domain, which are assumed to be independent to each other and have Rayleigh-distributed envelopes. The sub-channel models and emulators are based on a simple structure and characterized by flat fading. Through such decomposition approach, a frequency domain frequency-selective channel model can be achieved, which is suitable for an implementation of orthogonal frequency-division multiplexing (OFDM) or multi-carrier code-division multiplexing (MC-CDM) channel emulator on computer. In order to emulate the time-varying fading model well, the parameter sets are generated from time to time before the simulation with the same statistics.
