چکیده

Notch filters represent a method of estimating and/or tracking sinusoidal frequencies immerged in background noise. We shall refer to adaptive notch IIR filters, which make use of the RLS method. This paper presents an implementation of adaptive notch IIR filters on MOTOROLA StarCore140 DSP. We have used a modified RLS algorithm, more suitable for DSP implementation. The paper presents theoretical aspects but also focuses on implementation issues and experimental results.

Adaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm

 A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...

Narrow-band interference suppression in direct sequence spread spectrum systems using a lattice IIR notch filter

This paper proposes an algorithm for the suppression of narrow-band interference in direct sequence spread spectrum (DSSS) systems, based on the open loop adaptive IIR notch filtering. The center frequency of the interference is monitored on-line by the adaptive lattice IIR notch filter in [6] or by time-frequency analysis in [3]. The power of the interference signal is also estimated from the ...

Adaptive Detection of Narrowband Signals Using Frequency-Transformation-Based Variable Digital Filters

This paper presents an application of variable infinite impulse response (IIR) digital filters based on the Constantinides frequency transformation to adaptive filtering. We propose a new unified framework for adaptive detection of narrowband signals using variable band-stop IIR digital filters with arbitrary transfer functions. It is also shown that our proposed method includes the all-pass-ba...
