Digital modulation differents kind and aplications form them. Digital Modulation Techniques The techniques used to modulate digital information so that it can be transmitted via microwave‚ satellite or down a cable pair are different to that of analogue transmission. The data transmitted via satellite or microwave is transmitted as an analogue signal. The techniques used to transmit analogue signals are used to transmit digital signals

The idea of positioning of the receivers in deserts so that there is no interference in transmission and the main role of rectenna in conversion of energy is studied. This study discusses about the main technical challenge that is the construction of power satellites that uses electrical

Abstract: A cognitive radio (CR) network is a multiuser system. Cognitive users(CU) compete for limited resources in an opportunistic manner by interacting with each other for access to the available resources. In CR networks‚ proper power controlling is important to ensure efficient operation of both primary and cognitive users. In this paper‚ an algorithm is used to dynamically control transmission power‚ which is capable of achieving reasonably good solutions fast enough in order to guarantee

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers

TELECOMMUNICATION A Gower telephone‚ at the Musée des Arts et Métiers in Paris Telecommunication is the transmission of messages‚ over significant distances‚ for the purpose of communication. In earlier times‚ telecommunications involved the use of visual signals‚ such as smoke‚ semaphore telegraphs‚ signal flags‚ and optical heliographs‚ or audio messages via coded drumbeats‚ lung-blown horns‚ or sent by loud whistles‚ for example. In the modern age of electricity and electronics‚ telecommunications

A transmitter‚ plugged into a socket‚ generates radio waves. When the receiver attached to the device is set to the same frequency as the transmitter‚ it will charge the device’s battery. A universal wireless battery charger for portable and mobile devices can use ambient Radio Frequency (RF) or electromagnetic signals as a
