Title: Narrow band interference canceling apparatus for ds-cdma system
Inventor: CHO NAM IK
IPC: H04B1/71
Filed: 2001-04-19
Abstract: PURPOSE: An apparatus for eliminating a narrow-band interference signal in a DS-CDMA(Direct Sequence-Code Division Multiple Access) system is provided to suitably adjust a notch depth according to the strength of the interference signal and eliminate the interference signal using a lattice-type IIR(Infinite Impulse Response) notch filter. CONSTITUTION: A frequency estimator estimates a frequency of an interference signal included in an input signal of a CDMA receiver, and estimates a power of the interference signal from an output signal of an ALE(Adaptive Line Enhancer). A lattice-type IIR notch filter sets a filtering frequency of a zero point filter as the frequency estimated by the frequency estimator, adjusts the depth of a notch according to the estimated power, and eliminates the interference signal. A multiplier(303) multiplies an output signal of the lattice-type IIR notch filter by a spreading band signal(303A). A receiver(304) receives and processes an output signal of the multiplier(303).
