Introduction:
In this 21st century we required a multi functional system to operate on different platforms, which can access data easily, the main purpose of a Heterogeneous server is to establish a Heterogeneous network that can connect computers and other devices with different operating systems and/or protocols. For example, local area networks (LANs) that connect Microsoft Windows and Linux based personal computers with Apple Macintosh computers are heterogeneous. The word heterogeneous network is also used in wir ....etc

Turbo TCM Coded OFDM Systems for Non-Gaussian Channels



I. INTRODUCTION
Orthogonal Frequency Division Multiplexing (OFDM)
modulation has been a promising solution for efficiently
capturing multipath energy in highly dispersive UWB channels
and delivering high data rate transmission. The main
idea behind OFDM is to split the transmitted data sequence
into N parallel sequences of symbols. The transmission is
carried out in parallel on different frequencies which is a
desirab ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional F ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEE 802.11a in USA and H ....etc

SPARSE MULTIPATH CHANNELS: MODELING AND ESTIMATION

Waheed U. Bajwa, Akbar Sayeed, and Robert Nowak
Electrical and Computer Engineering, University of Wisconsin-Madison


ABSTRACT
Multipath signal propagation is the defining characteristic of terrestrial
wireless channels. Virtually all existing statistical models for
wireless channels are implicitly based on the assumption of rich
multipath, which can be traced back to the seminal works of Bello
and Kennedy on the wide-sense stationary uncorrelated ....etc
