DUAL LOOP DIGITAL PREDISTORTION FOR POWER AMPLIFIERS |
| 摘要 |
A method of predistorting an input signal (902) for an amplifier is disclosed (FIG. 9). The method includes predistorting the input signal with a first set of parameters (FDPD) and a second set of parameters (CDPD) at a first time (904). The first set of parameters is updated at a second time (914). The second set of parameters is updated separately from the first set of parameters at a third time (920). |

1. A method of predistorting an input signal for an amplifier, comprising the steps of:
predistorting the input signal with a first set and a second set of parameters; updating only the first set of parameters at a first time after the step of predistorting; and updating the second set of parameters at a second time. |
