Besides the allocation of a frequency range and several performance figures, there is no standardized transmission scheme so far. For the design of suitable physical layer techniques, comprehensive models are required to perform realistic link-level simulations for the aircraft environment. We present a wideband channel model for in-cabin WAIC systems, that has been derived from channel measurements performed in an Airbus A321 cabin. The model is validated by comparing physically measured frame error rates to simulated error ratesusing the proposed model in an OFDM transmission based on IEEE 802.11a applied to the WAIC frequency band.enhttp://rightsstatements.org/vocab/InC/1.0/channel measurementschannel modelwireless avionics intra-communicationssoftware-defined radioTechnology::629: Other Branches::629.1: Aviation::629.13: Aviation EngineeringTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic Engineering::621.38: Electronics, Communications EngineeringConference Poster not in Proceedingshttps://doi.org/10.15480/882.1605510.15480/882.16055Personal use of this material is permitted.
