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...
Current mode (CM) scheme provides suitable alternative for the high speed on-chip interconnect signaling. This paper presents a energy-delay optimization methodology for the current-mode (CM) signaling scheme. Optimization for the CM circuits for on-chip interconnects requires a joint optimization of driver and receiver device sizes, as their parameters which affect the energy-delay performance depend...
In this paper, a robust FGS video transmission scheme is proposed for streaming video over bandwidth-constrained packet loss channel, which aims to reducing both the overall distortion and quality fluctuation at the same time. We first use channel budget and packet loss property to determine the bits of enhancement layers that should be allocated per frame. Then unequal loss protection (ULP) using...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
In this paper, we focus on the security issue of a chaotic digital communication scheme called chaotic-pulse- position modulation. We design a third party intrusion scheme to test to see if CPPM is as secure as is claimed. Experiments are conducted with various chaotic maps, where CPPM is used to modulate the message at the transmitter and a Kalman filter fed with a polynomial approximation is used...
