A microcell interference model termed the Nakagami m,/m, is introduced in this paper. The desired signal as well as the cochannel interferers are assumed to have Nakagami statistics but with different amounts of fading. A special case of this model is obtained when the desired signal has Nakagami statistics while the cochannel interferers are subject to Rayleigh fading. The probability density ...

In this paper we demonstrate the rate gains achieved by two-tier heterogeneous cellular networks (HetNets) with varying degrees of coordination between macrocell and microcell base stations (BSs). We show that without the presence of coordination, network densification does not provide any gain in the sum rate and rapidly decreases the mean per-user signalto-interference-plus-noise-ratio (SINR)...

Let D be a b-wise independent distribution over {0, 1}m. Let E be the “noise” distribution over {0, 1}m where the bits are independent and each bit is 1 with probability η/2. We study which tests f : {0, 1}m → [−1, 1] are ε-fooled by D + E, i.e., |E[f(D+E)]−E[f(U)]| ≤ ε where U is the uniform distribution. We show that D+E ε-fools product tests f : ({0, 1}n)k → [−1, 1] given by the product of k...

In this study, efficient methods for optimal sensor placement (OSP) based on a new geometrical viewpoint for damage detection in structures is presented. The purpose is to minimize the effects of noise on the damage detection process. In the geometrical viewpoint, a sensor location is equivalent to projecting the elliptical noise on to a face of response space which is corresponding to the sens...

Resource allocation is studied for a forwardlink two-cell Code-Division Multiple-Access (CDMA) voice network with multiple service classes. System resources are transmitted power and codes. The service classes are specified by different user utility functions that relate utility to received Signal-to-Interference-plus-Noise-Ratio (SINR). The objective of the resource allocation is to maximize t...

Fractional frequency reuse (FFR) is an inter-cell interference coordination scheme that is being actively researched for emerging wireless cellular networks. In this work, we consider hexagonal tessellation based planned FFR deployments, and derive expressions for the coverage probability and normalized average rate for the downlink. In particular, given reuse 1 3 (FR3 ) and reuse 1 (FR1) regio...

AbstmctCochannel interference is one of the main impairments that degrade the performance of a wireless link. Power caintrol and antenna beamforming are two approaches for improving the performance in wireless networks by a p propriately controlling the cochannel interference. Joint o p timal beiimforming and power control scheme has been considered in previous work. It has been shown that the ...

Volume I first provides a compact survey on classical stochastic geometry models, with a main focus on spatial shot-noise processes, coverage processes and random tessellations. It then focuses on signal to interference noise ratio (SINR) stochastic geometry, which is the basis for the modeling of wireless network protocols and architectures considered in Volume II. It also contains an appendix...

Rapidly increasing traffic demand has forced indoor operators to deploy more and more Wi-Fi access points (APs). As AP density increases, inter-AP interference rises and may limit the capacity. Alternatively, cellular technologies using centralized interference coordination can provide the same capacity with the fewer number of APs at the price of more expensive equipment and installation cost....

Alternative risk premia (ARP) are designed to provide low-cost exposures long–short often embedded in hedge fund returns. This article describes the performance of ARP market form bank-provided total return swaps, which investable strategies that after-cost access ARP. Over 2010–20 period, many these provided significantly positive In addition, explain a high fraction returns on indexes, especi...
