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. Proposed approach is very effective and with moderate number of bits, a performance closed to optimum continuous beamformer can be obtained.

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 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...
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 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 SINGLE GROUP MULTICAST BEAMFORMING Demir, Özlem Tuğfe; Tuncer, Temel Engin (2014-05-09) 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.
