Abstract

The linearity of an envelope elimination and restoration (EER) transmitter depends primarily upon the bandwidth of the baseband envelope amplifier and path delay difference between the envelope and phase signals. A method for compensating the path-delay difference based on the baseband DSP technique has been proposed in this paper. This technique uses a baseband interpolation process to reduce the intermodulation effects of an EER transmitter. The improvements in spectral regrowth and waveform quality in the application to an IS-95 reverse link signal are demonstrated
