Abstract
Various techniques have been developed for different query types in content-based image retrieval systems such as sampling queries, constrained sampling queries, multiple constrained sampling queries, k-NN queries, constrained k-NN queries, and multiple localized k-NN queries. In this seminar , propose a generalized query model suitable for expressing queries of different types, and investigate efficient processing techniques for this new framework. We exploit sequential access and data sharing by developing new storage and query p ....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.

An Efficient and Fair Scheduling Scheme for
Multiuser OFDM Wireless Networks



Abstract

This paper proposes a new MAC scheduling scheme
for efficient support of multimedia services in multiuser OFDM
wireless networks, both in the uplink and in the downlink. This
scheme is based on a system of weights that dynamically accounts
for the experienced QoS and the transmission conditions in
an extended higher layers/MAC/PHY cross layer design.

Abstract— This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller AT89c52 at the heart of the system. The microcontroller is interfaced with GSM Modem via MAX232 level convertor. It is used to convert RS232 voltage levels to TTL voltage levels and vice versa. The hardware also has a 64K EEPROM chip AT24C64. This EEPROM ....etc

Near-Optimal Multiuser Detection in Synchronous CDMA Using Probabilistic Data Association
Presented By:
J. Luo, Student Member, IEEE, K. R. Pattipati, Fellow, IEEE, P. K. Willett, Senior Member, IEEE, and F. Hasegawa, Member, IEEE
Abstract
A Probabilistic Data Association (PDA) method is proposed in this letter for multiuser detection over synchronous code-division multiple-access (CDMA) communication channels. PDA models the undecided user signals as binary random variables. By approximating the inter-user interferenc ....etc

Multiuser Detection (MUD)
Abstract
Introduction
Multiuser Detection (MUD) techniques are one of the most important recent advances in communications technology. MUD deals with the optimal detection of mutually interfering digital streams of information that occur in various communication systems based on TDMA, FDMA, CDMA etc.In this project, the specific case of CDMA MUD based on pseudo-random signature sequences will be considered. Specifically, the MMSE optimization criterion will be considered in detail and the ....etc

A Low-Complexity SISO Multiuser Detector for Iterative Decoding of Asynchronous CDMA Systems With Convolutional Codes
Abstract”
The optimal decoding scheme for asynchronous codedivision multiple-access (CDMA) systems that employ convolutional codes results in a prohibitive computational complexity. To reduce the computational complexity, an iterative receiver structure was proposed for decoding multiuser data in a convolutional coded CDMA system. At each iteration, extrinsic information is exchanged between a soft-input soft-output (S ....etc
