The quest for higher spectral efficiency in wireless communications is creating a new impetus for selective and sensitive base-station receivers. One consequence of high selectivity is phase dispersion, which critically affects the operation of a pha

Compact high-temperature superconducting filters have high selectivity and sensitivity. Combined with a cryocooled low-noise amplifier, they significantly reduce the effective noise factor of a cellular base-station receiver. Their impact on wireless

Stability of excitons in undoped C 60 are studied from a molecular-solid point of view. The band edge of the electron–hole continuum is estimated theoretically to be located approximately at 2.0 eV. The predicted onsets for photoconductivity and op

Superconducting technology enables high-Q transmit filters for wireless base stations. However, superconducting filters are inherently nonlinear devices that cause signal distortion and spectral broadening. Third generation wireless CDMA2000 and WCDM

We examine the effect of higher receiver sensitivity on coverage of a code division multiple access (CDMA) cellular system. The reduced system noise figure of a base station is achieved by placing low noise amplifier (LNA) between receive antenna and

It is shown that a recently reported realization of trapping in a two-level system with frequency-modulated fields in quantum optics is intimately related to an earlier demonstration of dynamic localization of charges moving in a crystal under the ac

Summary form only given. Accumulating data for oxide superconductors which become superconducting at high temperatures continues to point to the strong involvement of (particularly local and dynamic) structural distortion. At the same time, recent ba

High-resolution Raman spectra excited from 1.45 to 1.75 eV are presented for solid C 60 films and crystals prepared by four methods. Intersample comparison shows that imperfections introduced in sample preparation can lower symmetries sufficiently to

We have studied a simple model of a nearly half-filled quasi-one-dimensional electron gas with both short-range electron-electron repulsion and retarded (phonon-mediated) attraction. We find that, as a function of doping (deviation from half-filling)
