ABSTRACT:
A digital demodulator which removes frequency and phase errors existing in a digital signal and converting the error-removed digital signal into a base band signal. The digital demodulator uses a frequency that is twice the transmission rate as the frequency of the sampling clock signal of an analog-to-digital (A/D) converter, and demodulates a received signal in a digital processing using the A/D converter which is low-speed. Thus, all of the received signal processing becomes digitized.
