Generic ultra-wideband (UWB) spread-spectrum system performance is evaluated in centralized and distributed spatial topologies comprising square-shaped indoor cells. Statistical distributions for link distances in single-cell and multicell configurations are derived. Cochannel-interference-induced outage probability is used as a performance measure. The probability of outage varies depending on...

This letter puts forth an analytical approach to evaluate the outage probability of power-based NOMA on the uplink of a 5G cell, the outage being defined as the event where the receiver fails to successfully decode all the simultaneously received signals. In the examined scenario, Successive Interference Cancellation (SIC) is considered and an arbitrary number of superimposed signals is present...

In this paper, we propose a new framework to study the performance of cellular networks using a fluid model and we derive from this model analytical formulas for interference, outage probability, and spatial outage probability. The key idea of the fluid model is to consider the discrete base stations (BS) entities as a continuum of transmitters that are spatially distributed in the network. Thi...

We consider multiple unmanned aerial vehicles (UAVs) serving a density of ground terminals (GTs) as base stations. The objective is to minimize the outage probability GT-to-UAV transmissions. Optimal placement UAVs under different UAV altitude constraints and GT densities studied.

We study the outage probability of opportunistic relay selection in decode-and-forward relaying with secrecy constraints. We derive the closed-form expression for the outage probability. Based on the analytical result, the asymptotic performance is then investigated. The accuracy of our performance analysis is verified by the simulation results.

Bluetooth is an emerging, short range, indoor wireless network technology, based on FH-CDMA/TDD, which allows a collection of devices to form small overlapping networks, called piconets, in an ad hoc fashion. It is likely that the Bluetooth specification may be adopted in the IEEE 802.15 Wireless Personal Area Network standard. In this paper, we present an analysis of the Bluetooth physical lay...

The outage probability is a key performance measure for real-time traffic in wireless networks, often considered as even more critical than the blocking probability. The blocking and outage probabilities do not have closed-form expressions as they depend in a too complex way on the traffic characteristics (call duration, bit rate requirement), the radio conditions (fading, shadowing, noise, int...

Level crossing rate, outage probability and fade duration of the SSC combiner output signal are determined in this paper. The presence of the Nakagami-m fading at the input is observed. The results are shown graphically for different variance values and decision threshold values. Key-Words: Diversity reception, Level Crossing Rate, Fade Duration, Outage Probability, Nakagami-m fading, SSC Combi...

Level crossing rate, outage probability and average time of fade duration of the SSC combiner output signal are determined in this paper. The presence of log-normal fading at the input is observed. The results are shown graphically for different variance values, decision threshold values and fading parameters.
