| Abstract: | In this paper, an L-band Ultra-wideband (UWB) TTC link for the Micro Air Vehicles (MAVs) is proposed. The structure of UWB-MAV TTC link system and the multipath channel model for wideband aeronautical communication are presented, considering the Direct Sequence Spread Spectrum (DSSS) modulation in the low-data single carrier-based impulse radio system. Taking into account the multipath and Doppler effects on the wideband DSSS signal, a lag Rake receiver capable of leveraging the diversity resulting from mobility is studied. The results show that a reliable UWB TTC link for MAVs can be established by compromising between range and performance of transmission. |
