Error models characterize the statistics of bursty error sequences encountered in digital wireless channels and are therefore, useful for the cross-layer design of wireless networks. In this paper, target error sequences are generated by computer simulations of multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) systems. A corresponding generative model is then d...

Application layer error resilience techniques in video communication are a relatively lightweight way of countering both isolated and burst error patterns. This paper systematically investigates their role. Flexible Macroblock Ordering (FMO) is shown to be an effective form of protection when errors are isolated but when burst errors are likely increasing the level of slicing is preferable. The...

This article describes low latency, zero overhead DFE burst error correction technique. Without any encoder or decoder the proposed technique makes use of existing pre-cursor ISI to detect and correct errors on a data. The implemented proof-of-concept 2-tap prototype in 65nm CMOS operates at 16 Gb/s compensates 32 dB loss consuming 58 mW only. With an additional 18 mW, receiver enables capabili...

Forward error correction (FEC) is a common error control technique to improve the quality of video streaming over lossy channels. To optimize the data recovery performance, frame-level FEC schemes have been proposed for streaming video to maximize playable frame rate (PFR) within transmission rate constraint on a random binary symmetric channel (BSC). However, burst loss is a commonplace in cur...

The paper presents necessary and sufficient condition on the number of parity-check digits required for the existence of a linear code capable of correcting errors in the form of 2-repeated low-density bursts occurring within a sub-block. An illustration of a code of length 24 correcting all 2-repeated low-density bursts of length 3 or less with weight 2 or less occurring within a sub-block of ...

If gamma-ray bursts originate in galaxies at cosmological distances, the host galaxy should be detected if a burst error box is searched deep enough; are the host galaxies present? We present and implement a statistical methodology which evaluates whether the observed galaxy detections in a burst’s error box are consistent with the presence of the host galaxy, or whether all the detections can ...

Correction of two-dimensional (2-D) and three-dimensional (3-D) error bursts finds wide applications in secure data handling such as 2-D and 3-D magnetic and optical data storage, charged-coupled devices (CCDs), 2-D barcodes, and information hiding in digital images and video sequences, to name a few. In this paper, we present a new 2-D interleaving technique, called successive packing, to comb...

Optical Burst Switching (OBS) is considered as a promising switching technique for the next generation of optical networks. A solid understanding of the characteristics of OBS traffic is the prerequisite to efficiently address a series of problems such as network dimensioning, performance optimization, routing and load balancing. In this paper we address this issue presenting the first exact an...
