In this paper we have developed a research model that illustrates the role of IT and
knowledge management in building an agile operation. Acknowledging that there is more …

We present a method for estimating the Doppler spread in mobile orthogonal frequency
division multiplexing (OFDM) systems. The estimation is based on finding the …

There have been many papers concerning about the peak to average power ratio (PAPR)
reduction and high power amplifier (HPA) linearization techniques for wireless OFDM …

Due to the increasing demand in mobile communications it is necessary to use the available
spectrum as efficiently as possible. In this paper we focus on the concept of overlay …

Many future airborne networks will be built around the software-defined joint tactical radio
system (JTRS). Because of the programmability of JTRS, planners of these networks will …

Broadband powerline communications over multi-wire overheard lines using orthogonal
frequency division multiplexing (OFDM) is considered in this paper. From earlier …

(OFDM), facilitating inexpensive receiver structures and high data throughput at the same
time, is emerging as a key radio transmission technology for wireless communications in …

Communications through frequency-selective fading channels suffer inter-symbol
interference (ISI), which limits the data rate. Complex equalizers are usually needed to …

We examine the potential use of several multicarrier (MC) and spread spectrum (SS)
systems for future aviation data links. These techniques are seeing widespread research …

In this report, we are going to outline several choices of Multiple Access (MA) techniques for
Uplink (UL) and Downlink (DL) for the 4th Generation (4G) systems. The basic …
