Multi-Carrier CDMA for Air Traffic Control Air/Ground Communication
We introduce MC-CDMA as a proposal for future VHF air traffic control air/ground communication. This technique permits the parallel operation of the current AM- and the proposed MC-CDMA system, because MC-CDMA does not require a continuous spectrum. Thereby, we also combat the narrow-band interferences by using the channel information to “soft erase” some sub-carriers. By considers the particular environment parameters used in air traffic control communication links we study the performance of our MC-CDMA system design in such a high interference environment. The numerical results show an acceptable, even when the number of interferers reaches 30% of the total bandwidth.
