Abstract:

New nonlinear characterization instruments associated with advanced digital signal processing algorithms turned digital predistortion, DPD, into the distortion cancellation method of choice to relax the linearity-efficiency compromise of wireless systems. Soon after its dawn, about some 15 years ago, it became both a well established practical technique and a typical example of the incorporation of signal processing algorithms for RF impairment mitigation in the present and future microwave and wireless systems. The goal for the fourth edition of this Student Design Competition (SDC) is to maximize the output power of an envelope tracking (ET) power amplifier (PA) under specific linearity constraints and realistic waveform operation. Following the three previous editions of the DPD Student Design Competition, a remote-controlled measurement setup (WebLab) consisting of the PA to be linearized and proper instrumentation will be made available for the competitors prior to IMS. Measurements can then be performed remotely using this virtual laboratory setup in order for the competitors to develop and tune their DPD algorithms.
