This method can overcome the multiple bandwidth regrowth issue in conventional DPD operation that normally places a burden on the 5G applications. By employing a coefficient pyramid, the proposed method can efficiently select the necessary core functions to build the nonlinear kernels according to the operation modes, which can largely reduce the power consumption and thus increase the system efficiency. Experimental results with 640MHz modulated signal proves that extending the DPD capability into the forthcoming 5G is possible.||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2017 European Microwave Association||Keywords:||Digital predistortion; 5G mobile communication; mmWave; Wideband; Power amplifiers||DOI:||10.23919/eumic.2017.8230719
