Doubly Constrained Robust Blind Beamforming Algorithm

We propose doubly constrained robust least-squares constant modulus algorithm (LSCMA) to solve the problem of signal steering vector mismatches via the Bayesian method and worst-case performance optimization, which is based on the mismatches between the actual and presumed steering vectors.The weight vector is iteratively updated with penalty for t

Effect of the structure of ethylene-propylene-diene-graft-polystyrene graft copolymers on morphology and mechanical properties of SAN/EPDM blends

Ethylene-propylene-diene-graft-polystyrene (EPDM-g-PS) copolymers were synthesized to obtain different structures of graft copolymers with different graft lengths and graft densities.The structure of synthesized EPDM-g-PS copolymers was characterized by gel permeation chromatography (GPC) and by Fourier transforms infrared spectroscopy (FTIR).These
