Abstract
A coding scheme for data is presented in which data is encoded and decoded such that a sequence of unconstrained input binary symbols, such as 1's and 0's, is encoded into a representation according to an alphabet comprising allowable time intervals between adjacent input binary symbols according to a precision parameter p, a minimum resolution parameter α, and resolution restriction functions L(t) and R(t), thereby defining a precision-resolution (PR) constrained code, and is modulated into an output signal comprising a waveform having signal peaks corresponding to the representation and separated according to the PR-constrained code for transmission of the output signal over the data channel. In this discussion, the minimum resolution parameter is denoted as a and is not limited to integer values.
