Abstract:
PLC technology based on an OFDM communication scheme is considered for data transmission between a control unit and actuators located in an aircraft wing. In order to optimize some OFDM parameters, transfer function measurements have been performed on an avionic test bench. Based on experimental values of the coherence bandwidth and of the channel delay spread, it appears that the subcarrier spacing can be larger than the spacing specified in HomePlug AV, which usually applies for in-house environment. Similarly, the duration of the cyclic prefix can be reduced. This will allow meeting the real-time and determinism constraints of avionic systems.
