Vida Vakilian is an Assistant Professor at California State University, Bakersfield (CSUB). Before joining CSUB,
she was a postdoctoral research fellow at University of California, Riverside.
She received her Ph.D. degree from University of Montréal, Canada, in Electrical Engineering in 2014.
In parallel to her Ph.D. studies, she has been working on several research topics in collaboration with industry and R&D laboratories.
From February 2013 to February 2014, she was a co-op Engineer at InterDigital Communications Inc.,
where she worked on design and development of advanced signal processing algorithms for the 3rd Generation Partnership Project (3GPP)
standards-based cellular systems. From August to December 2012, she was a research intern at Bell Labs, Alcatel-Lucent, Germany.
During this period, she contributed to 5GNOW project aiming to develop new robust PHY layer concepts, suited for future wireless systems.
From April to September 2011, she was a visiting scholar at University of California, Davis, and worked on analyzing and investigating
the performance of reconfigurable MIMO systems in spatially correlated frequency-selective fading channels.
During her studies, her works has been recognized with several prestigious scholarships and awards,
including DAAD-RISE Professional Scholarship, FQRNT Doctoral Research Scholarship, CREER International Internship Award,
ReSMiQ Supplementary Scholarship and SYTACom Industrial Collaboration Award.
VLSI Implementation of Low-complexity Detection Techniques for Multiple Antenna Systems.
The use of multiple antennas at both the transmitter
and the receiver of a wireless communication link enables high data rate transmission without
additional bandwidth or transmit power. However, the performance improvement obtained
comes at the cost of increased computational complexity at the receiver.
Design and implementation of a low complexity receiver requires co-optimization of the algorithm
with the underlying hardware architecture. Special attention must be paid to application requirements such
as throughput, latency, and resource constraints.
Millimeter-wave Wireless Communication for Fifth Generation (5G)
The millimeter-wave (mmWave) technology operating at frequencies in the 30 and 300 GHz
range is considered as a potential solution for the 5th generation (5G) wireless communication
systems to support multiple Gigabits per second data rates. The large communication bandwidth
available at mmWave frequencies allows users to transmit more data at
a given time compared with microwave-band wireless system with stringent bandwidth, where the
communication spectrum of each user is about a few MHz or less.
Coding Transmission Schemes for Next Generation of
Communication Systems via Reconfigurable Antennas
Over the past few years, studies have revealed that reconfigurable antennas can be used in conjunction
with multiple-input multiple-output (MIMO) technology to provide higher data rates and
better quality of services to a large number of users. In a reconfigurable MIMO system, the characteristics
of each antenna’s radiation pattern can be changed by placing switching devices such
as varactor diodes, or field-effect transistor within the antenna structure. As a result, a system
employing reconfigurable antennas is able to alter the propagation characteristics of the wireless
channel into a form that leads to a better system performance. In fact, by using reconfigurable
antennas and designing a proper code, we can achieve an additional diversity gain to further improve
the performance of wireless communication systems.
To cope with the growth of data traffic through mobile networks, efficient utilization
of the available radio spectrum is needed. In densely deployed radio networks,
User Equipments (UE) will experience high levels of interference which limits the
achievable spectral efficiency. In this case, a way to improve the achievable performance
is by mitigating interference at the UE side.
Advanced linear interference aware receivers are linear receivers able to mitigate
external co-channel interference.
Coordinated Multipoint Transmission and Reception in LTE-Advanced
Coordinated multi-point (CoMP) communication techniques
have been proposed for wireless communication systems (e.g.
in 3GPP LTE-Advanced standard) in order to mitigate
intercell interference and improve system performance
especially for cell-edge users. In multi-cell wireless
networks, CoMP achieves these objectives through
cooperation of multiple geographically separated base
stations (BSs), where the cooperation can be considered
in transmission of data in downlink or reception of users’
signals in uplink. Downlink COMP mainly uses joint
transmission (JT) or coordinated scheduling/coordinated
beamforming (CS/CB) approaches to effectively cancel
the interference. Uplink CoMP performs joint reception
(JR) where multiple BSs simultaneously process the
received signals from user equipments (UEs) to improve
the quality of detected signals.
I am seeking highly motivated graduate and under-graduate students who are interested to work on one of the above topics.
