1. A method of determining a frequency offset between components of a communications network based on a Constant Amplitude Zero Auto-Correlation, or CAZAC, sequence, the method comprising: providing, by a provisioning unit in a receiver stage, a set of correlation signals at different frequencies, each correlation signal being indicative of a specific frequency offset hypothesis and comprising the CAZAC sequence; receiving, at a radio frequency receiver of the receiver stage, a synchronization signal comprising the CAZAC sequence; correlating the synchronization signal with each of the correlation signals to obtain a correlation result for each frequency offset hypothesis; selecting at least one of the frequency offset hypotheses based on a comparison of the correlation results; and determining the frequency offset based on the at least one selected frequency offset hypothesis.
