Simulation Analysis on DPD Performance with DC Offset

Abstract:

DC offset of the input analog signal I and Q of quadrature modulator which is as DAC and RF channel interface will affect bit error rate (BER) of the system, the quality of the emission signals and the overall effect of DPD[. This paper focuses on the influences of non-ideal characteristics quadradure modulator on DPD technology.
