Adaptive Noise Cancellation Methods

Conventional approaches for suppressing sinusoidal interference in broadband signals typically employ notch filters, which require precise knowledge of the interference frequency. However, when the sinusoidal interference frequency varies slowly and stringent frequency selectivity is required, adaptive noise cancellation methods become preferable. This article presents a solution using a second-order FIR LMS adaptive filter for sinusoidal interference elimination, with implementation details covering filter design and weight update algorithms.
