Massive MIMO over Correlated Fading Channels: Multi-Cell MMSE Processing, Pilot Assignment and Power Control
Masoud Elyasi, Azadeh Vosoughi
We consider a multi-cell massive multiple-input-multiple-output (MIMO) system with correlated Rayleigh fading channels, where pilot reuse is permitted within each cell (to reduce p…
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…
On Distributed Linear Estimation With Observation Model Uncertainties
Alireza Sani, Azadeh Vosoughi
We consider distributed estimation of a Gaussian source in a heterogenous bandwidth constrained sensor network, where the source is corrupted by independent multiplicative and addi…
On M-ary Distributed Detection for Power Constraint Wireless Sensor Networks
Zahra Hajibabaei, Jalil Modares, Azadeh Vosoughi
We consider a wireless sensor network (WSN), consisting of several sensors and a fusion center (FC), which is tasked with solving an M-ary hypothesis testing problem. Sensors make…
On Bayesian Fisher Information Maximization for Distributed Vector Estimation
Mojtaba Shirazi, Azadeh Vosoughi
We consider the problem of distributed estimation of a Gaussian vector with linear observation model. Each sensor makes a scalar noisy observation of the unknown vector, quantizes…
On Distributed Vector Estimation for Power and Bandwidth Constrained Wireless Sensor Networks
Alireza Sani, Azadeh Vosoughi
We consider distributed estimation of a Gaussian vector with a linear observation model in an inhomogeneous wireless sensor network, where a fusion center (FC) reconstructs the unk…
Distributed Binary Detection over Fading Channels: Cooperative and Parallel Architectures
Nahal Maleki, Azadeh Vosoughi, Nazanin Rahnavard
This paper considers the problem of binary distributed detection of a known signal in correlated Gaussian sensing noise in a wireless sensor network, where the sensors are restrict…
