Digital predistorter (dpd) structure based on dynamic deviation reduction (ddr)-based volterra series |
| abstract |
The present invention provides a method and apparatus predistorting an input signal to compensate for non-linearities in an electronic device that operates on the input signal. The invention may be used, for example, to digitally predistort an input signal for a power amplifier in a wireless communication device. The predistorter (100, 200) uses a polynomial approach based on the well-known Volterra series to model the distortion function. A dynamic deviation reduction technique is used to reduce the number of terms in the distortion model and to facilitate implementation. The approach described herein eliminates square functions present in prior art designs and can be implemented using CORDIC circuits. |
