It has been predicted that the recent explosive growth in wireless data traffic will continue for foreseeable future. To date, attempts to address this have included increasing base station density through smaller cells, and a lesser extent, by improving spectral efficiency using close-to-capacity channel coding MIMO techniques. Providing further capacity coverage improvements ever shrinking cells could lead large infrastructure costs operating expenses. In paper we propose far less...

In this work we investigate quantum-enhanced target detection in the presence of large background noise using multidimensional quantum correlations between photon pairs generated through spontaneous parametric down-conversion. Until now similar experiments have only utilized one pairs' many degrees freedom such as temporal and number correlations. Here, both spectral achieved over an order magnitude reduction to turn significant data acquisition time when compared utilizing modes. We believe...

We describe a simple multivariate technique of likelihood ratios for improved discrimination signal and background in multi-dimensional quantum target detection. The combines two independent variables, time difference summed energy, photon pair from the spontaneous parametric down-conversion source into an optimal discriminant. discriminant performance was studied experimental data Monte-Carlo modelling with clear improvement shown compared to previous techniques. As novel detectors become...

Millimeter wave (mmW) communication has emerged as a promising component of the access link for 5G cellular systems. In order to overcome higher free-space path loss at these frequencies, high gain, and therefore highly directional, antennas are being proposed both ends link. Furthermore, in maintain mobile connection with an acceptable quality service (QOS), directional also need be electronically steerable. This required dual-end steerability adds significant system complexity terms...

Millimeter wave (mm wave) communication has emerged as a promising component of 5G cellular systems. The large losses in the Friis equation (due to implied small apertures mm antennas) suggest that high gain antennas are required. also implies steerability is Arrays patch one possible low cost solution, but each array limited angular field view. Multiple arrays per node can be used improve Choosing correct antenna configuration requires complex cost-benefit analysis and...

We calculate energy correlators in a general holographic model of confinement, involving an asymptotically anti-de Sitter (AdS) warped extra dimension. Building on recent computation minimal hard-wall we show that the shockwave method for efficiently computing AdS generalizes to arbitrary geometry. This is possible because exact, linear solutions 5D field equations exist any background. apply our formalism compute two-point correlator two simple models confinement with interesting infrared...

Millimeter wave (mmW) frequencies are considered to be indispensable for next generation wireless systems, both cellular and Wi-Fi, primarily due the large amounts of spectrum available in these bands. However, higher frequency-dependent path loss at needs overcome by use high-gain directional antenna arrays transmitter receiver.

Automatic Gain Control (AGC) system performance generally depends on the ability to accurately estimate receive signal power. The initial gain setting may be set high ensure that low power signals can detected. As Variable Amplifier (VGA) resides before Analog Digital Converter (ADC), there is a potential for heavy saturation at output of ADC, where this estimation normally performed. This will cause underestimated when using estimators do not account clipping, causing slow AGC convergence...
