ACOUSTIC NOISE CANCELLATION USING ADAPTIVE FILTERING


Abstract
All the physical systems when they operate produce physical noise, which is a mixing of an infinitive number of sinusoidal harmonics with different frequencies. So, the initial signal information is corrupted with this noise. This complex signal, may be very noisy, so much that the human ear or other system which may follow it, cannot receive correct the initial signal.

The Electrocardiogram (ECG) is a valuable signal recording the heart's electrical activity. The filtering quality of ECG signals directly affects the medical diagnosis. Since wavelet analysis can provide both time and frequency information, many nonlinear thresholding methods based on wavelet transform denoising have been applied to the noise reduction of ECG signals. However, most of these threshold shrinkage functions cannot adapt to different signals due to the fixed transition curve of threshold. Therefore, a novel genetic optimized wavelet ....etc

INTERFERENCE CANCELLATION IN ECG SIGNALS



INTRODUCTION

The Electrocardiogram (ECG or EKG) is a painless test that records the electrical activity of the functioning of the heart.
Based on ECG signal features, physicians diagnose different Arrhythmias .

Problem Definition

ECG signals in their acquisition process are affected by various types of noise.
Noise degrades the signal quality and change tiny features that may be critical for clinical monitoring and diagnosis.
The power line frequ ....etc

please, i need ccs code for noise cancellation

ABSTRACT
This paper explores the migration of adaptive filtering with swarm intelligence/evolutionary techniques employed in the field of electroencephalogram/event-related potential noise cancellation or extraction. A new approach is proposed in the form of controlled search space to stabilize the randomness of swarm intelligence techniques especially for the EEG signal. Swarm-based algorithms such as Particles Swarm Optimization, Artificial Bee Colony, and Cuckoo Optimization Algorithm with thei ....etc

I have some knowhow on noise cancellation in the receiver of radar or other communication system. But I don't know how to implement using FPGA for better result.
Now aday some projects have been performed on this area.but I am not clear about the future scope and how I can improve the scopes stated. If an MTech project proposal has been posted in IEE, I realy seek to know. ....etc

Low-Noise, Non-Contact EEG/ECG Sensor

Thomas J. Sullivan, Stephen R. Deiss, and Gert Cauwenberghs Division of Biological Sciences, University of California, San Diego La Jolla, CA 92093-0368 USA


Abstract Typical electroencephalogram (EEG) and electrocardiogram (ECG) sensors require conductive gel to ensure low-impedance electrical contact between the sensor and skin, making set-up time-consuming and long-term recording problematic. We present a gel-free, non-contact EEG/ECG sensor with on-board electrode that capacitively couples t ....etc

hi
i am implementing active noise control for a duct using C 6713. i need c++ code for it. or if someone can guide me becuase i have implemented C32 DSP but implementation of C6713 is different from C32.
