Calculations using oblate spheroidal raindrops, as well as measured data, demonstrated that rain-induced cross polarization amplitude is inversely proportional to frequency from 10 to 30 Ghz.

We report measurements of the second harmonic distortion in 1.3microns InGaAsP distributed feedback lasers.

Impairments, i.e., gain/phase imbalance and dc offset, in the analog quadrature modulator, can adversely impact the performance of a digital predistortion linearization system.

The linear response of a two-dimensional electron on a liquid helium film to a time varying electric field at zero temperature is calculated.

The concept of frequency diversity multiple-input and multiple-output (MIMO) detection is explained and the digital signal processing technique to utilize such concept is proposed.

We review the concept of frequency diversity MIMO detection in coherent optical transmission.

The purpose of the study is to develop an efficient 3GPP compliant method to simulate multiple independent fading radio channels in software defined Evolved Universal Terrestrial Radio Access Netwo

A ground state depleted (GSD) laser has been demonstrated at 912 nm in the form of a Q-switched oscillator operating on the Nd sup (3+) sup 4 F sub (3/2) - sup 4 I sub (9/2) transition in Y sub 2 S

For emerging TWDM-PON systems, based on burst-mode operation over WDM channels, a main challenge is the laser self-heating during bursts.

The various factors affecting the usability of mobile radio channels are discussed, and estimates are obtained for the number of usable channels per megacycle for several present and proposed metho
