We discuss the problem of estimating, at the mobile receiver, the weights applied by the base station transmitter when closed loop transmit diversity is used.
The Air Interface (AI) represents the complete Radio Access Network (RAN) protocol stack (i.e.
In this paper we present the development of a photonic integrated circuit on InP with an array of antenna-integrated uni-travelling carrier photodiodes to increase the output power levels.
A discussion of u.h.f. oscillations on spheres and ellipsoids, and a comparison of the mathematical theories of various authors.
[See Abstr. 1944B02151]. A general study of u.h.f. aerial problems, together with a critical discussion of the mathematical results obtained by various authors. The concept of back-e.m.f.
Anthropogenic effects on the space environment started in the late 19th century and reached their peak in the 1960s when high-altitude nuclear explosions were carried out by the USA and the Soviet
We report the design and implementation of Anti-Resonant Reflecting Optical Waveguides (ARROWs) in the InGaAs/InP system.
It is shown that the variation of side tone in an anti-side tone set is not under the control of the designer except in so far as the line impedance on which the set is to give optimum performance
This paper discusses the role of sigma* antibonding valence MO's in the electronic spectra of large molecules.
Feedback regulators as human artifacts have been here for a long time.
