In this letter, we propose an error-resilient transmission technique for the H.263 compatible video data stream, based on the data-partitioning technique. The proposed algorithm employs the bit rearrangement technique of the error-resilience entropy coding in each layer, providing unequal error protection against the channel errors, without requiring additional side information. In addition, we...

Accurate saccades require interaction between brainstem circuitry and the cerebeJJum. A model of this interaction is described, based on Kawato's principle of feedback-error-Iearning. In the model a part of the brainstem (the superior colliculus) acts as a simple feedback controJJer with no knowledge of initial eye position, and provides an error signal for the cerebeJJum to correct for eye-mus...

Internet multimedia applications have timing constraints that are often not met by TCP, the de facto Internet transport protocol, hence, most multimedia applications use UDP. Since UDP does not guarantee data arrival, UDP flows often have high data loss rates. Network data loss can be ameliorated by the use of Forward Error Correction (FEC), where a server adds redundant data to the flow to hel...

Reed–Solomon (RS) codes are widely used to identify and correct errors in storage systems and transmission and. When RS codes are used for so many memory system and reduces error in data. (255, 223) product ReedSolomon (RS) for non-volatile NAND flash memory systems. Reed-Solomon codes are the most used in digital data storage systems, but powerful for tool burst errors . To correct multiple ra...

We present Interplanetary Network localization information for 218 gamma-ray bursts in the 3rd BATSE catalog, obtained by analyzing the arrival times of these bursts at the Ulysses and Compton Gamma-Ray Observatory (CGRO) spacecraft. For any given burst observed by these two spacecraft, arrival time analysis (or “triangulation”) results in an annulus of possible arrival directions whose half-wi...

This paper considers the problem of Maximum a Posteriori (MAP) sequence equalization over a frequency selective channel when the channel is not perfectly known at the receiver. The imperfect channel estimate is provided by a least squares estimator using a training sequence (TS). The derivation of the MAP criterion taking into account the channel estimation error exists in the literature but no...

Modulation quality in most of digitally encoded cellular systems is examined by measuring the phase error and the frequency error of the transmitted signal. Phase error is an indication of how accurately the individual bits modulate the radio-frequency carrier; frequency error is the difference between the specified carrier frequency and the actual carrier frequency. The paper proposes a new te...

391 Abstract— Detection and correction of errors in digital data is an important issue for the modern communication systems. Therefore an efficient error control code is needed to protect the digital data. In high speed communication system Reed-Solomon codes are widely used to provide error protection especially against the burst errors. Reed-Solomon codes are cyclic, non-binary codes. In this...
