Topic: fuzzy based call admission control in wideband cdma cellular networks

ABSTRACT
In this paper, a novel call admission control (CAC) scheme using fuzzy logic is proposed for the reverse page link transmission in wideband code division multiple access (CDMA) cellular communications. The fuzzy CAC scheme first estimates the effective bandwidths of the call request from a mobile station (MS) and its mobility information, and then makes a decision to accept or reject the connection request based on ....etc

Hi,

I need some details regarding 'Wireless CDMA/GMS based Data Transmission'.
Basically a document/article explaining how it works practically and which are the products already available in the market.
What kind of data can be transmitted through this technology.?
Any technical limitations i may face later while using this in my project?

This is regarding a project which i want to work for my final year which is in the initial state.

Thanks in advance,
ZBasheera ....etc

1. INTRODUCTION
As more and more attention is paid to the ocean, the requirement of exploration and exploitation to it grows increasingly. In order to realize some tasks in the ocean such as collection of the information, monitoring of the environment, exploration of energy sources, forecast of natural disaster, assistant navigation, underwater communication technique has become a very important scientific research field. Because acoustic wave is adopted to actualize communication in the water instead of electromagne ....etc

SMS Based Wireless Electronic Notice Board using GSM/CDMA/3G Mobile Phone
ABSTRACT
Notice Board is primary thing in any institution / organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is a difficult process. A separate person is required to take care of this notices display. This project deals about an advanced hi-tech wireless notice board.
The project is built around the ATMEGA8L micro controller from Atmel. This micro ....etc

Fuzzy Logic and Fuzzy Sets 


History


Lotfi Zadeh, at the University of California at Berkeley, first presented fuzzy logic in the mid-1960's.

Zadeh developed fuzzy logic as a way of processing data. Instead of requiring a data element to be either a member or non-member of a set, he introduced the idea of partial set membership.

In 1974 Mamdani and Assilian used fuzzy logic to regulate a steam engine.

In 1985 researchers at Bell laboratories ....etc

Abstract
Wireless ad hoc networks provide a new dimension to computing by allowing a group of portable devices to talk to each other without any additional infrastructure and have been the focus of research in the area of wireless networks. CDMA has been gaining popularity as the multiaccess technique and is part of many wireless standards now. In this project we present techniques to improve performance of the CDMA based wireless ad hoc systems and present results based on extensive simulations. The resource utilization of network in ....etc

ABSTRACT
We propose a CDMA-based power controlled medium accessprotocol for mobile ad hoc networks (MANETs). Unlikepreviously proposed protocols, ours accounts for the multipleaccess interference (MAI), thereby addressing the notoriousnear-far problem that undermines the throughputperformance in MANETs. Channel-gain information obtainedfrom overheard RTS and CTS packets over an outof-band control channel is used to dynamically bound thetransmission power of mobile terminals in the vicinity ofa receiver. By properly estimating the requi ....etc

Abstract
In this work, we proposed a comparative analysis forthe performance-complexity tradeoff of several Hybrid Groupblindmultiuser detectors with polynomial expansion (MuDGroup-Blind PE). Using flop notation, the computacionalcomplexity for the three forms of SBld-MuD-II hybrid detectorbased on polinomial approximation was compared. MCS resultsindicated the superiority of the SBld-MuD-I detector in thepresence of parameters errors estimates and for the SBld-MuD-IIdetector with polinomial approach based on Gershgorin circles.
