Abstract: Systems and methods for increasing bandwidth capability of an envelope elimination and restoration (EER) transmitter. A frequency response of a power supply modulator of the transmitter is approximated. An inverse response is applied to the envelope signal prior to digital-to-analog conversion (DAC) and before the signal reaches the power supply modulator to pre-emphasize the signal thereby counteracting distorting affects of the modulator. The filter is implemented using any of a variety of different digital techniques including programmable logic, DSP, etc.
