ABSTRACT
A single-chip CMOS Global Positioning System (GPS) radio has been integrated using only a couple of external passive components for the input matching network and one external reference for the synthesizer. The receiver downconverts the GPS L1 signal at 1575.42 MHz to an IF of 9.45 MHz. The complete front-end and frequency synthesizer section have been integrated: low noise amplifier, image rejection mixer, IF active filter, and the full phase-locked loop synthesizer, including voltage-controlled osci ....etc

Abstract:

This Project is designed to track the various positions of the sun using telescope (with the help of LDRs). The LDR senses the intensity of sunlight and sends the output to the microcontroller through ADC. The microcontroller compares the various intensities and directs the telescope to point towards the direction of sunlight having maximum intensity. The rotation of the telescope is controlled by motors .The value of the intensity of different LDRs is displayed on the LCD ....etc

Abstract
Adaptive optics is a new technology which is being used now a days in ground based telescopes to remove atmospheric tremor and thus provide a clearer and brighter view of stars seen through ground based telescopes. Without using this system, the images obtained through telescopes on earth are seen to be blurred, which is caused by the turbulent mixing of air at different temperatures.
Adaptive optics in effect removes this atmospheric tremor. It brings together the latest in computers, material scie ....etc

Todayâ„¢s mobile professionals need to stay in regular contact with important sources of information such as the Internet, email, corporate networks and remote databases. As demand for Wide Area Networking (WAN) connectivity continues to grow, users and organizations are seeking ways to make it more efficient and productive. One of the most promising new technologies for this purpose is General Packet Radio Service (GPRS). GPRS is a packet-switching data network that is overlaid on the existing cellular voice network, using the same radio ....etc

Each mobile uses a separate, temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once, using one channel per mobile. Channels use a pair of frequencies for communication. One for transmitting from the cell site, the forward link, and one frequency for the cell site to receive calls from the users, the reverse link. Communication between mobile units can be either half-duplex or full-duplex. In case of half-duplex, transmit and receive communications between the mobile units are not at the same time, i.e. ta ....etc

ABSTRACT In the astronomy world, there is a need for high-performance radio telescopes operating at low frequencies. Such a telescope can be realized by a large network of small dipole antennas spread over an area of about 360 square kilometers. This antenna configuration requires a multi-terabit optical network to transport and collect the massive amounts of data picked-up from the sky. Within the Retina project, we have developed an architecture for such a multi-terabit optical network. In addition, new 160 Gbit/s line rate technology has be ....etc
