This paper treats the chaos synchronization problem of uncertain Lorenz system via single variable information of the master system. By the Lyapunov stability theory, the derived controller is featured as follows: (a) only single variable information of the master system is needed to transmit to slave system for synchronization; (b) the synchronization also(More)
This paper treats the chaos synchronization problem of uncertain chaotic Chua circuit system. Based on adaptive technique, the proposed controller is featured with (a) the only single variable information from the master system is needed; (b) the synchronization can also be achieved while some parameters of the master system are perturbed; (c) the bound of(More)
To meet the strict emission regulations, multipulse injection and other strategies were adopted to achieve different combustion patterns and paths of high-pressure common rail diesel engine in order to achieve ultra-low emissions. Therefore, the control system of multi-pulse fuel injection based on MCF5235 microprocessor and the multi-pulse control(More)
This paper presents an energy efficient VLSI architecture for motion estimation using image processing assisted voltage overscaling (VOS). Motion estimation is the most computationally expensive block inside any video encoder, typically consuming 40-60% of the total power. This work focuses on using VOS to reduce power consumption at the expense of marginal(More)
This paper presents a continuous phase modulation (CPM) coherent detector design suitable for high throughput, low power VLSI implementations. The key component of CPM coherent detector is the trellis decoder. Compared with the Viterbi algorithm, the sub-optimum T-algorithm significantly reduces computation complexity and provides great potential to realize(More)
