Abstract:
The method and system of digital timing correction in a digital baseband communication system is disclosed. In one embodiment, a method includes receiving samples at a predetermined time interval based on a current clock signal of a receiver clock, reading in a prompt sample of the received samples and a successor sample of the received samples based on a control signal, interpolating a projected sample based on the prompt sample, the successor sample and a predetermined time offset, determining the time offset for interpolation, by accumulating sampling frequency offset between the receiver clock and a reference clock, relative to a sample timing of the prompt sample, resulting in an interpolated data sample rate reduced by an integer multiple factor compared to a received sample rate and receiving a next sample of the received samples based on the current clock signal of the receiver clock.
