Interleavers [PDF]

open access: yes, 2006
The chapter describes principles, analysis, design, properties, and implementations of optical frequency (or wavelength) interleavers. The emphasis is on finite impulse response devices based on cascaded Mach-Zehnder-type filter elements with carefully designed coupling ratios, the so-called resonant couplers.

A Theory of Interleavers

open access: yes, 1997
An interleaver is a hardware device commonly used in conjunction with error correcting codes to counteract the effect of burst errors. Interleavers are in widespread use and much is known about them from an engineering standpoint.

Evolutionary Algorithm Aided Interleaver Design for Serially Concatenated Codes [PDF]

open access: yes, 2011
In this paper, we propose an algorithm for designing the interleavers of Serially Concatenated Codes (SCCs), in order to increase the Minimum Hamming Distance (MHD) between the legitimate permutations of the encoded bit sequence and hence to improve the ...

INTERLEAVING LOGIC AND COUNTING

open access: yesThe Bulletin of Symbolic Logic, 2023
AbstractReasoning with quantifier expressions in natural language combines logical and arithmetical features, transcending strict divides between qualitative and quantitative. Our topic is this cooperation of styles as it occurs in common linguistic usage and its extension into the broader practice of natural language plus ‘grassroots mathematics’.We ...

The Interleaved Genome

open access: yesTrends in Genetics, 2016
Eukaryotic genomes are pervasively transcribed but until recently this noncoding transcription was considered to be simply noise. Noncoding transcription units overlap with genes and genes overlap other genes, meaning genomes are extensively interleaved. Experimental interventions reveal high degrees of interdependency between these transcription units,

Interleaved Group Products [PDF]

open access: yesSIAM Journal on Computing, 2019
Let $G$ be the special linear group ${SL}(2,q)$. We show that if $(a_1,\ldots,a_t)$ and $(b_1,\ldots,b_t)$ are sampled uniformly from large subsets $A$ and $B$ of $G^t$, then their interleaved product $a_1 b_1 a_2 b_2 \cdots a_t b_t$ is nearly uniform over $G$. This extends a result of the first author [W. T. Gowers, Combin. Probab. Comput., 17 (2008),

Repeat accumulate code division multiple access and its hybrid detection

open access: yes, 2008
In this paper, we propose the novel concept of Repeat Accumulate Code Division Multiple Access (RA-CDMA), which employs unique, user-specific channel code generator matrices (interleavers) for differentiating the users.

Application of convolutional interleavers in turbo codes with unequal error protection

open access: yesJournal of Telecommunications and Information Technology, 2006
This paper deals with an application of convolu- tional interleavers in unequal error protection (UEP) turbo codes. The constructed convolutional interleavers act as block interleavers by inserting a number of stuff bits into the interleaver memories at
