Algoritmo de Conformação de Feixe Usando Projeção Adaptativa com Restrição Quadrática

This paper presents a new beamforming algorithm for mobile communication systems. Such an algorithm is developed by modifying the optimization problem used for developing the adaptive-projection constrained stochastic gradient (AP-CSG) algorithm. This modification consists of replacing an affine constraint by a quadratic one. As a result, the proposed algorithm, termed here quadratic AP-CSG (QAP-CSG), provides higher signal-to-interference-plus-noise ratio (SINR) than other similar algorithms from the literature. Simulation results are shown aiming to confirm the effectiveness of the proposed algorithm
