The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc

Open Wireless Architecture - The Core to 4G Mobile
Communications


Abstract


Mobile communication is continuously one of the
hottest areas that are developing at a booming speed,
with advanced techniques emerging in all the fields of
mobile and wireless communications. Current times
are just the beginning for deploying 3G mobile
communication systems, while research on the next
generation of mobile communications, 4G wireless and
mobile networks begin to pave the way for the future.
This article studies the visions of 4G from ....etc

Abstract

We investigate whether, and to what extent, the physical phenomenon of long-lifetime resonant electromagnetic states with localized slowly-evanescent field patterns can be used to transfer energy efficiently over non-negligible distances, even in the presence of extraneous environmental objects. Via detailed theoretical and numerical analyses of typical real-world model-situations and realistic material parameters, we establish that such a non-radiative scheme can lead to ‘‘strong coupling’’ between two medium-range ....etc

ABSTRACT”
In this Modern era, image Transmission and processing plays a major role. It would not be possible to retrieve information from satellite and medical images without the help of Image processing techniques. Image Enhancement is the art of examining images for identifying objects and judging their significance. The proposed work uses the concept of GA to find the image with best Signal to noise Ratio (SNR). The basic GA does not require extensive knowledge of the search space, such as likely solution bounds or functional derivat ....etc

Short Range Personal Radar
INTRODUCTION:
The idea to create a type of close proximity radar system came from a student in one of my classes. We went ahead and decided to streamline the idea into the course as one of the projects we'd build. After a week or two of prep time we finally agreed on the project setup & parts that we'd use. This is not meant to be an advanced project, thusly the difficulty is set at medium. Below is an example of what short range personal radar could be used for. It's meant to be a bit comical ....etc

This system uses RF transmission technology. The RF transceiver module which I use has a range up to 100 metres in ideal conditions. This module can transmit and receive 4-bit parallel data with or without 8 address bits using a specific encoder and decoder ICâ„¢s. Another module can be designed such that it can transmit and receive 8-bit parallel data with or without 10 address bits using a specific encoder and decoder ICâ„¢s. The advantage of having the address bits is that message transfer can be made secure.

different antennas have been developed and investigated for RKE (Remote Keyless Entry) and related automotive applications. These antennas include small printed-on-dielectric passive and active, printed-on glass, and whip-splitter types. Key antenna parameters-including size, performance, antenna shape-are proposed, investigated,The characteristics of small antennas taking into account the often significant effect of the cable length and direction position have also been investigated and are presented; solutions are also presented that eliminat ....etc
