    Web Based Audio/video Playback System Through Text Based SMS Using GSM and S3C2440

    In recent years, data service has been gaining popularity in embedded system. Most of the audio/video devices today consists of either a internal memory or consists of an interface in the form of I/O device and are being controlled by legacy Infra Red (IR) based remote controllers which has limited...

    LDPC Architecture Using Memory Bypassing Scheme

    Error correcting codes insert redundancy into the transmitted data stream so that the receiver can detect and possibly correct errors that occur during transmission. In VLSI design, area of the chip, speed and power consumption are. Its performance is close to Shannon's capacity limits. Inherent parallelism of the message passing...

    TDOA Computation Using Multicarrier Modulation for Sensor Networks With Efficient Bandwidth

    Locating accurate positions of the nodes is normally required in Sensor Networks which are attempting to locate and track an emitter or sources of signals. GPS is normally used as it provides high accuracy position measurement, but it has its own limitations. In this paper, the authors propose a Bandwidth...
