To reduce the peak-to-peak ratio (PAPR) requirements of RF components, single carrier (SC) modulation is adopted by Q-band mmWave communication. For SC communication, the fractional sampling clock offset influences link quality a lot. By inserting zero correlation zone (ZCZ) sequences between data symbols and doing equalization in frequency domain, the clock offset could be compensated at certain degree.
