Abstract
A coding method for a sequence of elements that can be equal to at least two distinct values, the elements forming at least one input symbol. The coding method comprises a stretching step of stretching at least one of the input symbols, to form a stretched symbol, such that the stretched symbol does not have any successive transitions. The coding method further comprises a cancelling step of canceling the disparity of the stretched symbol to form a coded symbol, such that the coded symbol comprises approximately the same number of elements of each value.
