What is sampling clock offset?

Sampling clock offset is the relative offset between the sampling period of transmitter and receiver. sro = -sco/(1+sco/1e6); % Sample rate offset in PPM. Model sampling clock offset, appending zeros to the waveform to allow for filter delay.

What is frequency offset in communication?

In radio engineering, a frequency offset is an intentional slight shift of broadcast radio frequency (RF), to reduce interference with other transmitters.
