We present a first-ever waveform-tracking receiver (RX) with type-II phase-tracking loop. In this preprint, a novel nonlinear filter in the feedback path is proposed to obtain better interference rejection performance. This digital nonlinear filter assists the receiver with tracking the waveform intelligently by predicting the incoming symbols; hence, we define this proposed RX as a waveform-tracking (WT)-RX. The simulation and preliminary measurement results are demonstrated in this paper. Moreover, we explore the issues of the current version WT-RX to provide guidance on possible future follow-up activities.
