In this paper we study the effects of practical pilot-assisted channel state estimation on the achievable information theoretic data rates (uplink and downlink) in a multiple antenna multiuser TDD

This paper studies the impact of additional pilot overhead for covariance matrix estimation in a time-division duplexed (TDD) massive multiple-input multiple-output (MIMO) system.

The impact of plasma-charging damage on ultra-thin gate-oxide is discussed. The argument for plasma-charging damage becomes less important is examined.

We report on the impact of PMD on the performance of single channel Nonlinear Compensation algorithms.

Tungsten-plug via failure is one of the key interconnect reliability issues, due to electromigration and stress migration concerns.

The impact of the spectral roll-off and the dispersion map on the peformance of dispersion-managed 50 GHz spaced 32GB PDM-QPSK WDM systems is experimentally studied.

The impact of pulse shapes on the performance of PDM-QPSK coherent transmission systems is discussed.

The impact of pulse shaping on the performance of 112-Gb/s polarization-division-multiplexed quadrature-phase-shift-keying (PDM-QPSK) coherent transmission systems in the presence of narrow bandwid

Electrical measurements of the noise figure of a fiber-optical parametric amplifier are presented and compared with optical measurements.

Bit error rate induced in a parametric amplifier has been measured with a 10 Gbit/s line rate.
