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.

Channel Estimation for OFDM System with Two Training Symbols Aided and Polynomial Fitting



INTRODUCTION

ORTHOGONAL frequency division multiplexing
(OFDM) is a high spectral efficiency transmission
scheme. It divides a wideband signal into many orthogonal
subcarriers and induces a symbol period that is much
longer than the bit duration. However, a long symbol
period is sensitive to the time-varying channel in wireless
communications. The channel response might change during

Abstract
With the increase of usage of wireless networks for purposes where the nodes are either stationary or minimally mobile, focus is also on increasing the network capacity of wireless networks. One such way is to use non-overlapping multiple channels provided by 802.11 by using multiple interfaces per node. Multiple nonoverlapped channels exist in the 2.4GHz and 5GHz spectrum. However, most IEE 802.11-based multihop ad hoc networks today use only a single channel. As a result, these networks rarely can fully exploit the aggregate ....etc

Performance analysis of channel estimation and adaptive equalization in slow fading channelPresented By:
Zhifeng Chen, Electrical and Computer Engineering, University of Florida
ABSTRACT
In our project, we first build up a wireless communication simulator including Gray coding, modulation, different channel models (AWGN, flat fading and frequency selective fading channels), channel estimation, adaptive equalization, and demodulation. Next, we test the effec ....etc

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
