Systematic Research on Adaptive NBI Cancellation of Wideband Wireless Links

Some wideband wireless links such as unmanned aerial vehicle (UAV) and satellite links have much wider bandwidth than that of high power natural or artificial interference. An idea of adaptive narrow band interference (NBI) cancellation based on different algorithms and structures aiming at wideband wireless links where bandwidth of interference is relatively narrow is posed here. All these theoretically feasible adaptive NBI cancellation schemes are simulated and tested based on different environmental parameters according to the real links. Moreover, performances of different adaptive NBI cancellation schemes are compared with each other.
