Now Murdoch, armed with spreading communications technology, is trying to pull off the same trick for all of Europe.
Elias Snitzer, a researcher at American Optical, demonstrated the first optical amplifier in 1961, but such devices were little used until the spread of communications based on fibre optics.
He was carried along by the same factors the spread of communications technology, the easier flow of goods over borders, international transfers of money with few questions asked that spurred globalisation.
A handful of pioneering women created the computing revolution, from the world's first computer programmer of the 1800s, Ada Lovelace, to Austrian-American Hedy Lamarr, Hollywood star and mathematician who invented an early technique for spread spectrum communications and frequency hopping – the basis for WiFi and Bluetooth we use today.
More than just debunking dot-com hyperbole, this starker assessment of the potential in the developing world for third-generation wireless contradicts the very basis of the International Telecommunications Union's plea 15 years ago for the new standard's development -- to accelerate the spread of communications.
Often, Walsh codes are considered for multiusers spread spectrum communications.
Theories of spread spectrum communications, channel coding, capacity analysis techniques have been widely applied in digital watermarking research.
It has been applied for non-stationary interference suppression in noise radar systems [6], as well as in spread spectrum communications [7], to achieve improved performance compared with that obtained by the STFT.
In particular, the following two standards are considered: the European Standard, ECMA-368 [8], for low-power and multimedia capable HDR WPANs based on UWB, and the IEEE 802.15.4 standard for LDR WPANs [9] based on spread spectrum communications.
