Designing an SOI Interleaver Using Genetic Algorithm

open access: yesPhotonics
A multi-objective genetic algorithm is tailored to optimize the design of a wavelength interleaver/deinterleaver device. An interleaver combines data streams from two physical channels into one. The deinterleaver does the opposite job.

Parallel concatenated block codes with flexible lengths and near-optimum performance

open access: yesInformation
The paper presents a modification of the interleaver used to construct Parallel Concatenated Block (PCB) codes with flexible lengths. This is accomplished for PCB codes whose interleaved message blocks have at most two bits of a message block.

Design and Evaluation of Adaptive (Serial/Parallel) Concatenated Convolutional Codes

open access: yesJournal of Engineering and Sustainable Development, 2006
In this paper, parallel Concatenated Convolutional Codes (PCCCs) is modeled as a special case of Serial Concatenated Convolutional Code (SCCCs). Consequently, resulting in Adaptive (parallel/serial) concatenated convolutional code in which the same ...
