| Abstract(in English) | A novel wideband digital predistortion (DPD) technique that can relax the requirement for sampling frequency is proposed. The proposed Spectrum-Decomposed Parallel Signal Processing DPD can reduce the sampling frequency to the half of normal DPD while compensating all nonlinear terms and achieve the same compensation performance. After presenting the principle and effect of the proposed scheme, the simulation results employing two-component carrier (2CC) LTE-A signal are presented. The proposed DPDs with four-band and two-band splitting methods can reduce their sampling frequencies to the half and two thirds of the normal DPD, respectively. |
