A method to adaptively detect passband-edge frequencies (PEFs) of band-limited signals is proposed and applied to estimating bandwidth of narrow-band interference signals in spread spectrum (SS) communication systems. It is first shown that a conventional method cannot detect PEFs of general band-limited signals except for lowpass signals. To solve this problem, differentiated mean output power of second-order IIR notch filter is proposed as the objective function. It is minimized or maximized by stochastic gradient (SG) algorithm to detect PEFs. A structure of the proposed adaptive filters is then derived. Finally bandwidth of narrow-band interference in an SS communication system is estimated by simulation and the validity of the proposed method is confirmed. |
