Two broadband amplifiers for 43 Gbit/s data transmission were realized in a SiGe-HBT technology with ft=120 GHz and fmax=100 GHz: a differential lumped limiting amplifier with 36 dB differential ga

Using different SiGe technologies, integrated circuits have been designed to realize electronic processing functions for 10 Gbit/s and 40 Gbit/s optical transmission systems.

New Optical transmission formats such as return-to-zero differential-phase-shift-keying have the potential to extend transmission distances (1).

The first research effort aimed at the growth of epitaxial SiGe thin films on Si substrates can be dated back to 1975, when Kasper et al[1] published their results of Si/Ge superlattice grown on Si

Concepts for the measurement of the temporal electric field of optical pulses are reviewed.

To fix ideas, consider the following conventional (baseband) PAM data-transmission scheme (see, for example, Ref. 1).

In this paper, transmitter diversity wireless communication systems over Rayleigh fading channels using pilot symbol assisted modulation (PSAM) are studied.

We consider the problem of detecting a deterministic signal in the presence of random transient disturbance and white Gaussian noise.

This paper reports on some properties of the solutions to the functional equation S 2 ( 0 = ^[Cs 2 (/) -F- S I ( / ) ] , where

For the analysis of adaptive routing (in particular, hot-potato routing) in packet-switched networks, it is important to know the number of paths of length k from any one node to another.
