Graphics Processing Units (GPUs) are widely used to accelerate data-intensive applications. To improve the performance of data-intensive applications, higher GPU memory bandwidth is desirable. Traditional GDDR memories achieve higher bandwidth by increasing frequency, which leads to excessive power consumption. Recently, a new memory technology called high-bandwidth memory (HBM) based on 3D die-stacking...
This paper proposes a framework for the artificial noise assisted secure transmission in multiple-input, multiple-output, multiple antenna eavesdropper (MIMOME) wiretap channels in frequency-division duplexed (FDD) systems. We focus on a practical scenario that only the eavesdroppers’ channel distribution information (CDI) is available and the imperfect channel state information (CSI) of the legitimate...
