Phase-only beamforming presents certain advantages in radar and communication systems. In cognitive radio, antenna and user selection are the two tools for increasing the quality of service (QoS) for the users. In this paper, discrete single group multicast transmit phase-only beamformer design is presented with antenna subset and user selection. The problem is converted into linear form and solved efficiently by using mixed integer linear programming to find the optimum subset of antennas and secondary users together with optimum beamformer phase coefficients. It is shown that significant power saving is possible compared to fixed antenna systems.

OPTIMUM DISCRETE PHASE-ONLY TRANSMIT BEAMFORMING WITH ANTENNA SELECTION
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2014-09-05)
Phase-only beamforming is used in radar and communication systems due to its certain advantages. Antenna selection becomes an important problem as the number of antennas becomes larger than the number of transmit-receive chains. In this paper, discrete single group multicast transmit phase-only beamformer design with antenna subset selection is considered. The problem is converted into linear form and solved efficiently by using mixed integer linear programming to find the optimum subset of antennas and bea...
Optimum discrete phase-only multicast beamforming with joint antenna and user selection in cognitive radio networks
DEMİR, ÖZLEM TUĞFE; Tuncer, Temel Engin (2015-11-01)
Spectrum underlay technique for secondary multicast network is an effective approach in cognitive radio. In such communication schemes, quality of service constraints are satisfied for the secondary users while interference to the primary users is kept under a threshold. Previous literature consists of suboptimum methods for the solution of the individual problems such as antenna and user selection. In this paper, the joint antenna and user selection problem is considered and solved in an optimum manner. Co...
Optimum Discrete Max-Min Style Broadcast Beamforming Design
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2014-04-25)
In this paper, max-mm style transmit beamformer design for single group multicast (broadcast) scenario is considered. The phase and amplitude values of beamformer vector coefficients are selected from finite discrete sets. With the help of integer variables, original optimization problem is converted to a linear form appropriate for mixed integer linear programming. The solution is always feasible as long as the total power is above a certain value. Branch and cut strategy guarantees the optimum solution. P...
Optimum discrete transmit beamformer design
DEMİR, ÖZLEM TUĞFE; Tuncer, Temel Engin (2015-01-01)
In this paper, transmit beamformer design problem is considered for single group multicast case. This problem is treated in discrete phase and amplitude and converted to a linear form. The solution of this linear optimization problem is always feasible as long as the total transmit power is above a certain value. The proposed method is guaranteed to find the optimum solution. This new approach is used to design discrete phase-only (DPOB) and discrete phase-amplitude beamformers (DPAB). It is shown that the ...
Active vibration control of beam and plates by using piezoelectric patch actuators
Lüleci, İbrahim Furkan; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2013)
Conformal airborne antennas have several advantages compared to externally mounted antennas, and they will play an important role in future aircrafts. However, they are subjected to vibration induced deformations which degrade their electromagnetic performances. With the motivation of suppressing such vibrations, use of active vibration control techniques with piezoelectric actuators is investigated in this study. At first, it is aimed to control the first three bending modes of a cantilever beam. In this s...
