In this paper, a new complex adaptive notch filters using the oscillator based algorithm has been proposed. The approach presented for second-order real coefficient IIR filters has been applied to derive a coefficient-update algorithm for a first-order complex adaptive notch filter. Convergence characteristics of the proposed algorithm have been analyzed. Unbiased frequency estimation of a complex sinusoid has been achieved by thinning the notch bandwidth. Computer simulations show the effectiveness of the proposed algorithm. |
