1. A digital predistortion (DPD) system for pre-distorting an input to a non-linear system, comprising:
a digital predistortion circuit configured to receive input data and modify the input data using at least one look-up table, wherein the at least one look-up table is addressed by a signed real value of the input data, wherein the signed real value of the input data ranges from a negative value to a positive value; and
a memory configured to store the at least one look-up table.
