摘要: In this letter, a novel phase discriminator called digital phase discriminator (DPD) is proposed for 1-bit analog-to-digital-conversion (ADC) software-defined receivers. Using fewer computations, the DPD achieves higher accuracy than that of the typical arctangent phase discriminator (APD). The improvement is up to several orders when the sampling frequency keeps increasing since the accuracy of APD is bounded mainly due to quantization loss. Finally, the simulation results demonstrate the superiority of the proposed approach and the critical uniformity condition is verified.
