A study of recursive least squares (RLS) adaptive filter algorithm in noise removal from ECG signals
2015 International Conference on Informatics, Electronics & Vision (ICIEV), 2015Electrocardiogram (ECG) is a diagnostic procedure that measures and records the electrical activity of heart in detail. By reviewing an ECG report, one's condition of heart can be evaluated. But ECG signals are often affected and altered by the presence of various noises that degrade the accuracy of an ECG signal and thus misrepresents the recorded ...

The abdominal ECG is a composite signal because it contains both the mother's and the fetus' ECG signals, but the chest ECG is supposed to have only maternal (MECG) component. In this paper, we use three different adaptive algorithms to remove FECG signal from the abdominal ECG.

Iterative equalization using optimal Multi-User Detector (MUD) & trellis-based channel decoder in coded Code Division Multiple Access (CDMA) systems improves Bit Error Rate (BER) performance. When large number of users is employed in the system over multipath channels, causing significant Multiple-Access Interference (MAI) & Inter Symbol Interference ...

Student Conference on Research and Development, 2003
This paper analyses two types noise cancellation algorithms (i.e. the least-mean square (LMS) algorithm and the recursive least-squares (RLS) algorithm) and tries to outlines their strengths and their weaknesses. We have implemented these algorithms in a "semi-hardware" fashion, using a microphone, two loudspeakers and a Sound Blaster sound card and ...

A multichannel adaptive lattice algorithm is derived that provides a least-squares estimate of a primary signal in terms of the last p samples of m reference signals. The recursions developed are optimized for multichannel use and provide an algorithm with computational complexity O(pm/sup 2/).

The fast QR-decomposition based recursive least-squares (FQRD-RLS) algorithms offer RLS-like convergence and misadjustment at a lower computational cost, and therefore are desirable for implementation on a fixed-point digital signal processor (DSP). Furthermore, the FQRD-RLS algorithms are derived from QR-decomposition based RLS algorithms that are ...

Spectral Estimation Using Improved Recursive Least Square (RLS) Algorithm: An Investigational Study
2015In the area of signal processing, spectral efficiency has played a contributory role for analyzing the spectrum with respect to time and frequency. For the purpose of enhancing the spectrum to maximize the amount of signal to be transmitted on minimal transmission errors, there are significant research works being introduced in last decades.

Total least squares parameter estimation is an alternative to least squares estimation though much less used in practice, partly due to the absence of efficient recursive algorithms or parallel architectures. Here it is shown how previously developed systolic algorithms/architectures for recursive least squares estimation can be used for recursive ...

The recursive least squares (RLS) adaptive algorithm is combined with the "adaptive threshold nonlinear algorithm" (ATNA) proposed by the author (Koike, S., IEEE Trans. Sig. Processing, vol.45, p.2391-5, 1997), to derive RLS-ATNA, resulting in improvement of the convergence rate of the ATNA that offers robust adaptive filters in impulse noise ...
