An enumerative method for runlength-limited codes: permutation codes
Permutation codes, introduced by Slepian, were shown to perform well on an additive white Gaussian noise (AWGN) channel. Unfortunately, these codes required large lookup tables, making them quite complex to implement even though the maximum-likelihood decoder is very simple. In this correspondence, we present an enumeration scheme which encodes and decodes permutation codes with low complexity....
متن کاملBraun and Janssen: On the Low-Frequency Suppression Performance of DC-Free Runlength-Limited Modulation Codes ON THE LOW-FREQUENCY SUPPRESSION PERFORMANCE OF DC-FREE RUNLENGTH-LIMITED MODULATION CODES
Basic trade-offs between the rate of combined DC-free runlength-limited (DCRLL) modulation codes and the amount of suppression of low-frequency components are presented. The main results are obtained by means of a numerical study of dependencies between statistical properties of ideal, ‘maxentropic’ DCRLL sequences. The numerical results are mathematically founded by proving the observed behavi...

متن کاملRunlength Limited Codes for Single Error-Detection and Single Error-Correction with Mixed Type Errors
Runlength-limited (RLL) codes are used in magnetic recording. The error patterns that occur with peak detection magnetic recording systems when using a runlength-limited code consist of both symmetric errors and shift errors. We will refer to shift errors and symmetric errors collectively as mixed-type errors. In this correspondence, a method of providing error control for mixed-type errors tha...
متن کاملAlmost-Certainly Runlength-Limiting Codes
Standard runlength-limiting codes – nonlinear codes defined by trellises – have the disadvantage that they disconnect the outer errorcorrecting code from the bit-by-bit likelihoods that come out of the channel. I present two methods for creating transmissions that, with probability extremely close to 1, both are runlength-limited and are codewords of an outer linear error-correcting code (or ar...
