Figure 11From: Efficient Lookup Table-Based Adaptive Baseband Predistortion Architecture for Memoryless NonlinearityPSD performance of a complex-gain LUT predistorter trained using LCNLMS with linear (LIN) and nearest-neighbor (ZOH) interpolation in the feedback predistorter. Input waveform is a 10 MHz LTE OFDM signal.Back to article page
