For the remaining guard band spectrum, guard band power limits are used.

Guard band power limits for FDD

The displacement of the control slide (6) is effected, for example, by means of rebound straps.

In embodiments of a first type, the guard band expander includes at least one harmonics generator (40, 54, 60), which acts as a frequency multiplier and generates harmonics either of the down-converted signal or of the FM signal before heterodyning.

Therefore, the guard bandwidths can be used to open new channels upon which information can be transmitted.

For remaining spectrum in the guard bands (i.e. not covered by transitional regions or not used for PPDR or M2M radio communications), guard band power limits are used.

Techniques for performing data detection and decoding in a manner to account for guard subbands are described.

The guard bands are biased to reduce the coupling ratio to zero and thereby enable starting and improved performance.

An FM detection system receives an FM input signal containing a tuned carrier separated by guard bands from side carriers.

Blocks of encoded audio information are arranged in frames separated by gaps or guards bands that are aligned with frames of video information.

Guard bands are unused areas of the spectrum that insulate one signal from another.

Similarly, the transmitter or receiver of the RF TRXs is configured to operate in a frequency band outside of all said guard bands.

The Department is hereby adopting a 71-76 GHz and 81-86 GHz band plan that consists of 250 MHz channels and 125 MHz guardbands.

In the data recording regions, data tracks are raised and adjacent data tracks are separated by recessing guard bands (20 - 20).
