چکیده
Abstract This paper presents the construction of RLL-ECCs (run length limited error control codes) from three selected ECCs specified by Consultative Committee for Space Data Systems (CCSDS) optical communications. The obtained present a practical alternative to CCSDS codes with pseudo-randomizers. Their advantage is that maximal run lengths equal symbols in their codeword sequences are guaranteed, which not case if common approach pseudo-randomizers used. other advantages no additional redundancy introduced into encoded codewords and encoding decoding procedures original do have be modified following cases: Firstly, hard used transmission channel can modeled as BSC (binary symmetric channel) secondly, soft coherent BPSK phase shift keying) modulation appropriate model an AWGN (additive white Gaussian noise) channel.

Construction for obtaining trellis run length limited error control codes from convolutional codes
Recently a new construction of run length limited block error control codes based on control matrices of linear block codes was proposed. In this paper a similar construction for obtaining trellis run length limited error control codes from convolutional codes is described. The main advantage of it, beyond its simplicity is that it does not require any additional redundancy except the one which...

متن کاملThe power spectrum of run-length-limited codes
In this paper, a novel method is developed for computing formulae for the power spectra associated with run-length-limited (RLL) codes. Explicit use is made of a compact description of the run-length process associated with the RLL code. This association simplifies the general derivation of the power spectrum. The calculation of the spectra of several RLL codes popular in data storage applicati...
متن کاملBinary permutation sequences as subsets of Levenshtein codes, spectral null codes, run-length limited codes and constant weight codes
We investigate binary sequences which can be obtained by concatenating the columns of (0,1)-matrices derived from permutation sequences. We then prove that these binary sequences are subsets of a surprisingly diverse ensemble of codes, namely the Levenshtein codes, capable of correcting insertion/deletion errors; spectral null codes, with spectral nulls at certain frequencies; as well as being ...
