We demonstrate a quantum confined Stark effect (QCSE) electroabsorption modulator consisting of quantum wells of AlGaAs and GaAs on an epitaxial multilayer dielectric mirror, all grown by molecular
Semiconductor multiple quantum wells (MQWs) have opto-electronic properties enhanced over bulk semiconductors.
The high demand for frequency resources due to the ever increasing number of devices in cellular networks requires new approaches that maximize the spectral efficiency.
We have detected a second high velocity bipolar flow in B335 located to the east of the core and its associated bipolar flow.
We present a new method for determining the frequencies of the earth's free oscillations.
The primary challenge in wireless communication with energy harvesting devices is to efficiently utilize the harvesting energy such that the data packet transmission could be supported.
In a previous paper,1 we reported on the estimation of the parameters of tones from a finite number of noisy, discrete-time observations and described the case of a single complex tone.
A MTMR capacity survey has been performed in Manhattan, New York, for cellular applications. Shannon capacities close to the Rayleigh i.i.d. have been measured.
We have examined the efficiency within wireless access options for mobile devices and discovered that a classical pitfall is revisited.
In this work we provide an information-theoretic analysis of a Gaussian multiple-input multiple-output multiple access channel (MIMO MAC) with imperfect channel knowledge at the receiver.
