Abstract
A digital predistortion system and method for pre-distorting an input to a non-linear system. The digital predistortion system includes a digital predistortion circuit and a memory. The digital predistortion circuit is configured to receive input data and modify the input data using at least one look-up table. The at least one look-up table is addressed by a signed real value of the input data. The memory is configured to store the at least one look-up table. The at least one look-up table is implemented based on a generalized memory polynomial model.
Claims15
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.
A method for pre-distorting an input to a non-linear system, comprising:
- receiving input data;
- and
- modifying 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.
