Constrained codes are widely used in digital transmission systems and digital recording systems to generate constrained sequences with properties that comply with the given physical characteristics of the transmission or recording channels. The power spectral density (PSD) of encoded signals often plays an important role in the design of constrained codes.(More)
In order to minimize the interference between adjacent data arrays recorded in the same holographic volume, the patterns of 1's and 0's in each data array should be t- conservative, i.e., for a prescribed integer t, there should be at least t transitions of the form 1 rarr 0 or 0 rarr 1 in each column and row of the data array. In this paper, we present(More)
