Delay spread characterization of millimeter-wave indoor backscattering channel [PDF]

2016 10th European Conference on Antennas and Propagation (EuCAP), 2016
In this paper we present two indoor measurement campaigns performed using millimeter-waves massive arrays in a corridor and in an office room. In particular, we characterize the delay spread of the backscattered channel responses which can be exploited in future personal radars applications for indoor localization and mapping.

Frame delay and loss analysis for video transmission over time-correlated 802.11A/G channels [PDF]

, 2007
This paper presents simulation results for the transmission of unicast MAC frames over 802.11a/g. Fading channel models at various Doppler frequencies are developed to generate time- correlated SNR waveforms.

Linearity considerations in adaptive antenna array applications [PDF]

, 1995
The use of adaptive antenna in mobile communications base stations is self-explanatory. It offers the potential of increased spectrum efficiency, extended range of coverage and reduced delay spread.

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Correlation of delay spread and CCIR impairment

Electronics Letters, 1995
CCIR impairment is a subjective measure of the degradation of television images caused by ghosting. Delay spread is the standard deviation of the impulse response of a multipath channel. To compare the impairment and delay spread, measurements were taken of independent real channels through the use of widely-spaced frequencies and decorrelated ...
