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.

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 (SISO) ....etc

A NEW ITERATIVE SPEECH ENHANCEMENT SCHEME BASED ON KALMAN FILTERING



ABSTRACT

A new iterative speech enhancement scheme that can be seen as an approximation to the Expectation-Maximization (EM) algorithm is proposed. The algorithm employs a Kalman filter that models the excitation source as a spectrally white process with a rapidly time-varying variance, which calls for a high temporal resolution estimation of this variance.

ABSTRACT
In today s business where speed is of essence, an iterative development approach that
allows the functionality to be delivered in parts has become a necessity and an effective
way to manage risks. In an iterative process, the development of a software system is done
in increments, each increment forming of an iteration and resulting in a working system. A
common iterative approach is to decide what should be developed in an iteration and then
plan the iteration accordingly. A somewhat different iterative is approach is to ....etc

Abstract:
The combination of antenna array beamforming with multiuser detection can effectively
improve the detection efficiency for wireless communications under multipath interference,
especially for the applications in a fast fading channel. The authors study the performance of an
adaptive beamformer incorporated with a B-MMSE detector, which works on a unique signal
frame characterised by training sequence preamble and data blocks segmented by zero-bits. Both
the beamformer weight updating and B-MMSE detection are carried out ....etc

Near-Optimal Multiuser Detection in Synchronous CDMA Using Probabilistic Data Association
Presented By:
J. Luo, Student Member, IEE, K. R. Pattipati, Fellow, IEE, P. K. Willett, Senior Member, IEE, and F. Hasegawa, Member, IEE
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 interference (IU ....etc
