Abstract :
A novel algorithm for the canceling of broadband multi-path interference was presented, namely IBF-ANC (Inverse Beamforming & Adaptive Noise Canceling) combined algorithm. The interference was reconstructed by IBF and used to be the reference at the input end of adaptive noise canceller, which overcame the defect of ANC algorithm. As many practical experiences showed that it was very difficult for ANC algorithm to acquire the exact reference input. Compared with IBF or ANC alone, the combined algorithm could obtain much performance improvement, and the target signal hidden in the strong interference could also be detected, just as the simulation results showed.
