Spectrum decision is the ability of a cognitive radio (CR) to select the best available
spectrum band to satisfy secondary users'(SUs') quality of service (QoS) requirements …

Inefficient spectrum usage is a crucial issue in wireless communications and methods for
dynamic spectrum access are proposed based on spectrum sensing methodology of the …

Spectrum sensing is a critical function for enabling dynamic spectrum access (DSA) in
wireless networks that utilize cognitive radio (CR). In DSA networks, unlicensed secondary …

Autoregressive Integrated Moving Average (SARIMA) Model, which models the power
reception of different channels of the Global System for Mobile Communications (GSM) …

Objectives: The analysis of spatial opportunities to reuse frequencies by secondary users
(SU) in a Cognitive Radio (CR) network is the main objective of this work. Methods/Statistical …

We discuss implementation aspects of a software-defined radio system that allows for
dynamic waveform reconfiguration during runtime without interrupting data-flow processing …

With the rapidly-increasing amount of high data rate wireless devices, technologies and
services appearing on the market today, there is an increasing demand for the wireless …

This paper presents the development and evaluation of two linear algorithms for forecasting
reception power for different channels at an assigned spectrum band of global systems for …

Cognitive Radios (CRs) are devices, which should be cognizant about the Spectrum Holes
upon which the idea of a CR resides, which relates to the sensing and channel management …

One key goal of software-defined radio (SDR) is to provide the possibility of operating in a
wide range of frequency bands with a single device. At the same time, real-world …
