Amplifier linearization using predistortion
Abstract:
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.
