This paper proposes a new approach to analyze crosstalk of coupled interconnects in the presence of process variations. The suggested method translates correlated process variations into orthogonal random variables by principle component analysis (PCA). combined with polynomial chaos expression (PCE), the technique utilizes Stochastic Collocation Method (SCM) to analyze the system response of coupled...
In this paper, we propose an improved rate control scheme for low delay H.264 video coding. A fast and best selection of initial QP is first proposed in the GOP layer rate control. Then, an improved MAD prediction model and overhead bits prediction method is adopted in the MB layer rate control. The simulation results show that the proposed scheme gives an average PSNRY gain of about 0.55 dB when...
This paper addresses adaptive channel estimation for time-varying mobile wireless channels with nonstationary statistics. We presents a reduced complexity adaptive channel estimator based on a set membership filtering approach known as the Optimal Bounding Ellipsoid (OBE) algorithm. To exploit time and frequency domain correlation properties of the channel in an efficient low-complexity way, we allow...
