CO CHANNEL INTERFERENCE REDUCTION IN GSM
Introduction to Cellular Systems
 Solves the problem of spectral congestion and user capacity.
 Offer very high capacity in a limited spectrum without major technological changes.
 Reuse of radio channel in different cells.
 Enable a fix number of channels to serve an arbitrarily large number of users by reusing the channel throughout the coverage region.

CELL PHONE INTERFERENCE IN IR PLANES

Presented By:
K.RAJESH KUMAR N.VIDYA SAGAR REDDY

R.G.M.C.E.T.
Abstract:

The advent of cell phones has made single connected network.Communications between people have become an easier task and hence there is growth every where.But this use of cellular communication is restricted in airplanes due to the threat that cell phones frequencies might interfere with that of the air planes electronic equipments(cockpit electronics) In this paper we have proposed ....etc

Reliable Adaptive Modulation and Interference Mitigation for
Mobile Radio Slow Frequency Hopping Channels

Abstract—

The Long Range Fading Prediction algorithm for
Slow Frequency Hopping (SFH) systems is proposed and demonstrated
to enable combined Adaptive Modulation and adaptive
Frequency Diversity to mitigate the effects of fading and partialband
interference. Significant performance gains are demonstrated
relative to non-adaptive methods in realistic mobile
radio SFH channels where the total ba ....etc

ABSTRACT
Image inpainting refers to filling in the missing parts or modifying the damaged parts of an image in a visually plausible way.‘Image inpainting’, an artistic term used from ancient times, refers to restoration or retouching works of paintings. This technique can be used for restoring the missing parts of an image or for removing the unwanted objects from an image. In digital images, role of image inpainting techniques grow from mere restoration of images, photographs and films to powerful image enhancement and image comp ....etc

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
