In this paper, transmit beamformer design for single group multicast scenario is considered. The problem is solved in discrete form where the beamformer phase and amplitude values are selected from finite discrete sets. Original optimization problem is converted to a linear form by introducing new variables. The solution of the equivalent optimization problem is always feasible as long as the total power is above a certain value. The problem in its linear form is guaranteed to return optimum solution. Proposed approach is very effective and the number of bits can be increased to obtain close to optimum continuous phase and amplitude beamformers.

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 ...
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...
Joint Discrete Phase-Only Broadcast Beamforming With Antenna Selection
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2014-04-25)
In this paper, single group multicast (broadcast) phase-only transmit beamformer design with antenna subset selection is considered. The problem is converted into a linear form and solved efficiently by using mixed integer linear programming to find the optimum subset of antennas and beamformer vector. Several experiments are done and it is shown that the proposed approach is effective and efficient.
OPTIMUM DESIGN OF DISCRETE TRANSMIT PHASE ONLY BEAMFORMER
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2013-09-13)
Transmit beamformer design usually results suboptimum bearnformers in multicast scenario. In this paper, discrete phase only beamformer design is considered. The design problem is cast in such a form that the solution is always feasible and optimum beamformer can be found using the branch and cut algorithm. Beamformer phase terms and their interrelations are expressed with a set of cosine vectors which lead to linear set of constraint equations that can be solved with mixed integer linear prograrmning. It i...
Optimization techniques for nonconvex problems and optimum discrete transmit beamformer design /
Demir, Özlem Tuğfe; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2014)
In this thesis, transmit beamformer design is investigated for single group multicast scenario. The problem is considered for both discrete and continuous case. The discrete problem is converted to a linear form in which there are both discrete and continuous variables. The resulting mixed integer linear programming problem is optimally solved with much lower computational complexity than brute force search. For practical reasons, robust version of the problem is also elaborated and solved with mixed intege...
