Abstract :
This paper presents a wireless aircraft cabin system operating in the 2.4 GHz ISM band and uses cognitive radio techniques to increase system robustness by actively and dynamically avoiding interfering signals in the same frequency band. The implementation of the basic cognitive radio functions spectrum sensing, policy enforcement and decision making, as well as their integration on a software defined radio platform together with the communication functions is presented and discussed. Finally, the cognitive approach is validated using a demonstrator setup and a controlled interference scenario.
