Abstract:
OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers and sent simultaneously in time. The result is an optimum usage of bandwidth. A set of orthogonal sub-carriers together forms an OFDM symbol. To avoid ISI due to multi-path, successive OFDM symbols are separated by guard band. This makes the OFDM system resistant to multi-path effects. Although OFDM in theory has been in existence for a long time, recent developments in DSP and VLSI technologies have made it a feasible opti ....etc

NAVSYS has developed a new Digital Antenna Element design for integration with a Controlled Reception Pattern Antenna (CRPA) which offers significant advantages over conventional Digital Antenna Electronics for high integrity GPS applications such as the Joint Precision Approach and Landing System (JPALS). Instead of performing spatial processing within the Digital Antenna Electronics, the Digital Antenna Elements each output the raw sampled digital data from each of the CRPA antenna raw sampled digital data from each of the CRPA antenna eleme ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Abstract— In this paper, the indirect matrix converter is
systematically studied with the single-pole-multiple-pole
representation. A carrier based PWM algorithm is developed
in two steps. First, the continuous modulation functions for all
the throws are derived based on the desired sinusoid ....etc

SYNOPSIS
Using an experimental system that mimics stone fragmentation in the renal pelvis, the role of stress waves and cavitation in stone comminution in shock-wave lithotripsy (SWL) is noted. Spherical plaster-of-Paris stone phantoms (10mm Dia) were exposed to 25, 50, 100, 300 and 500 shocks at the beam focus of a Dornier HM-3 lithotripter. The stone phantoms were immersed either in degassed water or in castor oil to delineate the contribution of stress waves and cavitation to stone comminution. It ....etc

Introduction

OFDM: a form of MultiCarrier Modulation.
Different symbols are transmitted over different subcarriers
Spectra overlap, but signals are orthogonal.
Example: Rectangular waveform -> Sinc spectrum
