The radiation sensitivity of integrated memory cells increases dramatically as the supply voltage decreases. Although there are some Error Correcting Code (ECC) studies to prevent faults on memories used in space applications, there is no consensus o

Large-scale antenna systems offer many attractive features, including large array gain and improved spatial resolution, for example. However, classical beamforming methods, such as the linearly constrained minimum variance (LCMV) filter, do not perfo
