This document defines new RTP payload formats for the Forward Error Correction (FEC) packets that are generated by the non-interleaved and interleaved parity codes from a source media encapsulated in RTP. These parity codes are systematic codes, where a number of repair symbols are generated from a set of source symbols. These repair symbols are sent in a repair flow separate from the source fl...
Introduction A new image-based ghost correction technique is described for general interleaved EPI. It estimates the phase distortions causing the ghosts as a general function of (x,y), even in the presence of significant overlap of parent image and ghosts. If the phase distortion is assumed to be a function of x (frequency encode direction) only, the new technique is similar to a recently publ...
In this paper Bresenham's line drawing algorithm on interleaved grid is proposed. It uses the advantages of interleaved sampling to scan-convert the pixel on the raster with less
Previous research has suggested that studying categories in either interleaved or blocked fashion can be beneficial for inductive learning. These conflicting results can be explained by considering that different category structures benefit differentially from blocked or interleaved study (Carvalho & Goldstone, 2013). However, memory-based theories have related the advantage of interleaved stud...
A novel group of interleaved orthogonal frequency division multiplexing (IL-OFDM) and partial transmission IL-OFDM (PT-IL-OFDM) schemes are proposed for optical coherent detection. In the interleaved operation, the odd (or even) subcarriers of an OFDM symbol are reserved (closed). Such an interleaved arrangement can gain the tolerance toward phase noise induced interchannel interference (PN-ICI...
We propose an area-efficient high-speed interleaved Viterbi decoder architecture, which is based on the state-parallel architecture with register exchange path memory structure, for interleaved convolutional code. The state-parallel architecture uses as many add-compare-select (ACS) units as the number of trellis states. By replacing each delay (or storage) element in state metrics memory (or p...
This work shows that the cryptanalysis of the shrinking generator requires fewer intercepted bits than that indicated by the linear complexity. Indeed, whereas the linear complexity of shrunken sequences is between A·2(S−2) and A·2(S−1), we claim that the initial states of both component registers are easily computed with less than A · S shrunken bits. Such a result is proven thanks to the defi...
To significantly increase the sampling rate of an A/D converter (ADC), a time interleaved ADC system is a good option. The drawback of a time interleaved ADC system is that the ADCs are not exactly identical due to errors in the manufacturing process. This means that time, gain and offset mismatch errors are introduced in the ADC system. These errors cause non harmonic distortion in the sampled...
Interleaved Reed–Solomon codes are applied in numerous data processing, data transmission, and data storage systems. They are generated by interleaving several codewords of ordinary Reed–Solomon codes. Usually, these codewords are decoded independently by classical algebraic decoding methods. However, by collaborative algebraic decoding approaches, such interleaved schemes allow the correction ...
Time interleaved A/D converters (ADCs) can be used to increase the sample rate of an ADC system. However, a problem with time interleaved ADCs is that distortion is introduced in the output signal due to various mismatch errors between the ADCs. One way to decrease the impact of the mismatch errors is to introduce additional ADCs in the interleaved structure and randomly select an ADC at each s...
