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

We present a new model for multiple input multiple-output (MIMO) out door wireless fading channels which is more general and realistic than the usual i.i.d. model. We investigate the channel capacity as a function of parameters such as the local scattering radius at the transmitter and the receiver, the distance between the transmit (TX) and receive (RX) arrays, and the antenna beamwidth sand spacing. We point out the existence of pinhole channels which exhibit low fading correlation between antennas but still have poor rank properties and henc ....etc

The Java Media Framework API (JMF and JMF-RTP) enables audio, video and other time-based media to be added to Java applications,, JMF is JAVA MEDIA FRAMEWORK . It is fundamentally an API for handling audio and video. Java Media Framework (JMF) provides a unified architecture and messaging protocol for managing the acquisition, processing, and delivery of time-based media data. JMF is designed to support most standard media content types, such as AIFF, AU, AVI, GSM, MIDI, MPEG, QuickTime, RMF, and WAV.

MIMO Wireless Channels

Multiple-input multiple-output (MIMO) communication techniques make use of multi-element antenna arrays at both the TX and the RX side of a radio page link and have been shown theoretically to drastically improve the capacity over more traditional single-input multiple output (SIMO) systems . SIMO channels in wireless networks can provide diversity gain, array gain, and interference canceling gain among other benets.

In addition to these same advantages, MIMO links can offer a multi ....etc

Real-time video transmission over ad hoc networks faces many challenges in cluding low bandwidth, long end-to-end delay, high packet loss rate, frequently changing topology and limited-powered mobile nodes. This paper presents an effective real-time video transmission scheme and improves implementation of DSR (Dynamic Source Routing) protocol. set up a test-bed by using DSR routing in the IP layer, and an application transmitting video stream over UDP protocol. We get a continuous JPEG image stream from a ZC0301p web camera and split each image ....etc

Abstract

Wireless technology has become the most exciting area in telecommunication and networking. The rapid growth of mobile telephone use, various satellite services, and now the wireless Internet are generating tremendous changes in telecommunications and networking. Wireless is convenient and often less expensive to deploy than fixed service, but wireless is not perfect. There are limitations, political and technical difficulties that may ultimately prevent wireless technologies from reaching their full potential. Regardless of t ....etc
