    This paper reviews some important technologies for speech and audio coding, contrasting time domain and frequency domain processing. These technologies have contributed to the standardization activities in ITU-T and ISO/IEC MPEG, respectively. It is interesting that the standardization targets for speech and audio have started to converge recently. The MPEG USAC (Unified Speech and Audio Coding) s... View full abstract»

  • A novel voltage controlled crystal oscillator circuit

    Publication Year: 2009, Page(s):329 - 333
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1682 KB) | HTML iconHTML

    A novel approach reported in this paper optimizes the dynamic noise and drive sensitivity factor for achieving low phase noise VCXO circuits. An example of mode-feedback and differential coupled crystal oscillators are demonstrated for the validation of this approach, which minimizes the phase noise for inexpensive low quality factor (Q) crystal resonator based oscillators. The noise reduction tec... View full abstract»

    Rapid changes in technology have provided many challenges for the medical and educational systems of Japan, a modern, cosmopolitan country with a sizable and sometimes isolated rural population. We have developed a communications system in an attempt to solve some of the problems created by this social division. Herein, we show examples of some possible uses of this MuTA system, with examples of o... View full abstract»

    Wireless sensor networks have significant potential in the home environment. Home application scenarios include monitoring and interaction from several remote or local devices such as mobile phones, televisions or computers. In this paper we propose an architecture for a network based on IP-enabled wireless sensors. The communication system is based on the XMPP-protocol which is shown to be highly... View full abstract»

  • Novel driving method to improve picture quality of active-matrix organic light-emitting diode displays

    Publication Year: 2009, Page(s):259 - 262
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (347 KB) | HTML iconHTML

    A novel driving method is proposed to improve the picture quality of active-matrix organic light-emitting diode displays. A pulse-width modulation with current uniformization is presented to overcome the non-uniform characteristics and degradation phenomena of thin-film transistors and organic light-emitting diodes. Its working and effect are confirmed using an actual pixel equivalent circuit. View full abstract»

  • Blind carrier phase correction algorithms for 8-VSB signals

    Publication Year: 2009, Page(s):398 - 402
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (445 KB) | HTML iconHTML

    A blind carrier phase derotator can be employed to correct and track carrier phase offset either before or after equalization in a blind adaptive receiver. This paper proposes a computationally efficient blind carrier offset recovery algorithm for 8-vestigial side-band (8-VSB) signals by designing its cost function such that its cost surface has only two global minima without any undesirable local...

    It has been well recognized as an efficient approach for broadcasting popular videos by partitioning a video data stream into multiple segments and launching each segment through an individual channel simultaneously and periodically. Based on the design premises, the slotted generalized Fibonacci broadcasting (SGFB) scheme allows a client with small bandwidths to receive video segments. Given a fi... View full abstract»

    Vertical pixel mixture charge coupled device (VPMix-CCD) is with a built-in vertical pixel mixing technology to average two vertically-neighboring components of a color filter array (CFA) image within the same color filter. This paper addresses the interpolation problem for the noisy VPMixCCD image. A novel approach is proposed to exploit the hidden Markov tree (HMT) model and the minimum mean squ...

    The present study applies to FM radio receivers. Estimating the energy of a FM modulated signal by the Teager-Kaiser nonlinear energy operator (TEO), it is possible to detect, mitigate and/or suppress the effect of multipath on the signal captured by antenna at the receiving set.

    AODVjr (AODV junior) is a simplified specification of AODV (ad hoc on-demand distance vector) routing protocol and suitable for ZigBee network. To enhance its routing strategy in a ZigBee network, in this paper, we proposed an AODVjr routing protocol with multiple feedback policy by means of processing main message during route discovery. The source node starts the route discovery, the destination... View full abstract»

    The purpose of this research is to use an FLC (fuzzy logic controller) to manage the power consumption of a notebook or an UMPC (ultra mobile PC). The FLC not only controls the LCD backlight and the speed of the fan to reduce the power consumption but also lengthens the battery recharge cycle. The EC (embedded controller) in a notebook is a device to assist the onboard power management system whic... View full abstract»
