Steady-State Rate-Optimal Power Adaptation in Energy Harvesting Opportunistic Cognitive Radios with Spectrum Sensing and Channel Estimation Errors
Hassan Yazdani, Azadeh Vosoughi
We consider an opportunistic cognitive radio network, consisting of Nu secondary users (SUs) and an access point (AP), that can access a spectrum band licensed to a primary user. E…
Achievable Rates of Opportunistic Cognitive Radio Systems Using Reconfigurable Antennas with Imperfect Sensing and Channel Estimation
Hassan Yazdani, Azadeh Vosoughi, Xun Gong
We consider an opportunistic cognitive radio (CR) system in which secondary transmitter (SUtx) is equipped with a reconfigurable antenna (RA). Utilizing the beam steering capabilit…
Power Adaptation for Distributed Detection in Energy Harvesting WSNs with Finite-Capacity Battery
Ghazaleh Ardeshiri, Hassan Yazdani, Azadeh Vosoughi
We consider a wireless sensor network, consisting of N heterogeneous sensors and a fusion center (FC), that is tasked with solving a binary distributed detection problem. Each sens…
Source Localization and Tracking for Dynamic Radio Cartography using Directional Antennas
Mohsen Joneidi, Hassan Yazdani, Azadeh Vosoughi +1
Utilization of directional antennas is a promising solution for efficient spectrum sensing and accurate source localization and tracking. Spectrum sensors equipped with directional…
On the Spectrum Sensing, Beam Selection and Power Allocation in Cognitive Radio Networks Using Reconfigurable Antennas
Hassan Yazdani, Azadeh Vosoughi
In this paper, we consider a cognitive radio (CR) system consisting of a primary user (PU) and a pair of secondary user transmitter (SUtx) and secondary user receiver (SUrx). The S…
Beam Selection and Discrete Power Allocation in Opportunistic Cognitive Radio Systems with Limited Feedback Using ESPAR Antennas
Hassan Yazdani, Azadeh Vosoughi, Xun Gong
We consider an opportunistic cognitive radio (CR) system consisting of a primary user (PU), secondary transmitter (SUtx), and secondary receiver (SUrx), where SUtx is equipped with…
