frequency offset

frequency offset

[¦frē·kwən·sē ′ȯf‚set]
(communications)
Change in the frequency received on a transmission line from that which was transmitted, which can occur if suppressed-carrier multiplexing is used, and may result in errors.
A small difference in the carrier frequencies of television stations in adjacent cities operating on the same channel.

In addition, a frequency offset with a random carrier frequency is applied to each signal.
The key issue is how to estimate the frequency offset, time delay, amplitude and phase offset.
The phase noise of the proposed VCO is 20 dB lower than that in [7] for the same basic design structure and at the same frequency offset.
By using a tiny frequency offset among antenna elements, FDA can achieve an angle-range-dependent beamforming [10].
In the FDA antenna, we have uniform amplitude weightings and/or nonuniform weightings and uniform frequency offsets and nonuniform frequency offset.
f is the frequency offset. 2[pi]([T.sub.[DELTA]] + T')f denotes the compensation for group delay.
In order to design an accurate system, time and frequency offset algorithms in [13] are used.
For the OFDM modulation, the normalized frequency offset factor is used to measure frequency offset.
A problem that can arise from this technique is the assignment of the upper and lower integration frequency offset limits.
where P[(f).sub.DVBT] is DVB-T signal spectrum mask, P[(f).sub.LTE] - LTE signal spectrum mask, [f.sub.max] is maximum integration frequency offset of DVB-T spectrum mask and [f.sub.off] is frequency offset between center frequency of victim and interfering signals.
In OFDM system, Carrier Frequency Offset (CFO) is used to maintain the orthogonality between the subcarrier in the desired frequency range, which results in Inter Carrier Interference (ICI).
