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.

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-Minimized Multipath Routing with Congestion Control in Wireless Sensor Network for High-Rate Streaming - IEEE TRANSACTIONS ON MOBILE COMPUTING, VOL. 7, NO. 9, glomosim

Abstract—
High-rate streaming in WSN is required for future applications to provide high-quality information of battlefield hot spots. Although recent advances have enabled large-scale WSN to be deployed supported by high-bandwidth backbone network for high-rate streaming, the WSN remains the bottleneck due to the low-rate radios used and the effects of ....etc

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

ABSTRACT :-
A SQUID (for superconducting quantum interference device) is a very sen
isitive magnetometer used to measure extremely weak magnetic fields, based on superconducting loops containing Josephson junctions.
SQUIDs are sensitive enough to measure fields as low as 5 aT (5×10−18 T) within a few days of averaged measurements. Their noise levels are as low as 3fT•Hz-½. For comparison, a typical refrigerator magnet produces 0.01 tesla (10−2 T), and some processes in animals produce very small magne ....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
