What is carrier phase offset?

This is the phase difference of the carrier phase of a pattern item relative to the carrier phase of another pattern item. If only one pattern item defines a pattern then the phase offset is relative to the carrier.

What is offset in telecom?

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

What is offset in VHF?

The difference between the repeater's receive frequency and its transmit frequency is called the offset.

What is carrier frequency offset in OFDM?

Carrier frequency offset (CFO) is one of most well-known disturbances for OFDM. It generates inter-carrier interference (ICI) and degrades OFDM performance [1]. In order to mitigate the negative influence, CFO is usually estimated and compensated accordingly during OFDM reception.
