ABSTRACT
The term echo cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network.



Two sources of echo have primary relevance in telephony:
acoustic echo and
hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appe ....etc

how to calculate interference power?
I saw a formula in matlab(mathworks.in)
website as:
Interference power=total power-noise power-signal power.
Is this a basic formula?

Abstract
Frequency offsets or frequency spreads distort theorthogonality between sub-carriers, which results in inter-carrierinterference (ICI), in regular OFDM communication systems. Inorder to combat the impact of ICI on OFDM systems, an ICImitigation technique by jointing symbol shift cancellation (SSC)and adjacent sub-channel interference filter (ASIF) is proposedin this paper. At first, the symbol shift cancellation (SSC) methodis used to cancel the impact of ICI on the far sub-carriers, andthen the adjacent sub-channel interferen ....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 freq ....etc
