the title of the tallest man-made structure in the world‚ a title it held for 41 years‚ until the Chrysler Building in New York City was built in 1930. However‚ due to the addition‚ in 1957‚ of the antenna atop the Eiffel Tower‚ it is now taller than the Chrysler Building. Not including broadcast antennas‚ it is the second-tallest structure in France‚ after the Millau Viaduct.The tower has three levels for visitors. Tickets can be purchased to ascend‚ by stairs or lift‚ to the first and second levels

shift keying (MPSK) for MIMO decode-and forward (DF) relay system. Based on moment generating function (MGF) of output symbol to noise ratio (SNR) of overall system SER is derived. In this paper‚ we consider an nt -antenna at the source S‚ an nr -antenna at the relay R and nd -antenna at the destination D‚ where the propagated signal from the source passes through keyhole and correlated channel. The same orthogonal space time block codes (OSTBC) is applied to source -destination‚ sourcerelay and

CHAPTER 1 THE PROBLEM AND ITS BACKGROUND Introduction The changing needs of people led to the development of a means to make tasks a lot easier and more convenient. This is technology. It is a tool that now plays an important role in people’s everyday life. Because of this technology every complicated task is now provided with an equal solution. Hence‚ the difficulties that people experience in doing tasks are minimized. It is not impossible that in the near future‚ these difficulties will be

Abstract: In this paper‚ we present the concept of transmitting power without using wires i.e.‚ transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission (MPT). This paper is mainly concentrated on : i) The most popular concept known as Tesla Theory‚ ii) The microwave power transmission(MPT) called Solar power satellite‚ and iii) The highly efficient fiber lasers for wireless power

It describes a circuit for the transceiver at frequency 2.45 GHz and its interfacing with a computer. A brief note about the specifications of the antenna used and an introduction to the transponder design are made. 2 RFID in ETC RFID – a review The basic working of an RFID is well described in Fig. 1 below.

RFID BASED ATTENDANCE CUM SECURITY SYSTEM [pic] Submitted By: INTRODUCTION Our final year project is RFID based Attendance cum Security System. This idea came to my mind when I saw our lecturers taking the attendance of 100s of students very hardly. We thought we can integrate the RFID based Security System with attendance system as well. That what our final year project is doing. BLOCK DIAGRAM OF THE PROJECT: [pic] History of RFID: In a very interesting article

detection (MCMUD). The ‘multichannel’ term indicates that the receiver incorporates multiple antennas by using space-time-frequency adaptive processing. The article reports the experimental performance of these codes and receivers. M - multiple-output (MIMO) systems are a natural extension of developments in antenna array communication. While the advantages of multiple receive antennas‚ such as gain and spatial diversity‚ have been known and exploited for some time [1‚ 2‚ 3]‚ the
