AMPLIFIER LINEARIZATION USING PREDISTORTION |
| 摘要 |
A device and method of predistortion linearization that account for both EVM and spectral mask are disclosed. The device and method are based on transforming the predistorter optimization problem from the time domain to the frequency domain, and weighting the equations according to one or more desired objectives. One objective focuses on abiding by the spectral mask, whereas another objective focuses on improving the EVM. |

1. A device for linearizing an output of a power amplifier, the device comprising:
an input interface for a source signal; a circuitry adapted to distort the source signal by applying one or more frequency domain equations involving one or more parameters affecting the output of a power amplifier, to provide an output signal inversely distorted according to the nonlinearity of the output of the power amplifier; and an output interface for the output signal. |
