FACCHDedicated channel for control information | ||
FadingVariation of signal attenuation with various variables, e.g. caused by multipath propagation, probabilistic | |
Fading marginDesign allowance value that provides for sufficient system gain or sensitivity to accommodate expected fading | |
Far fieldField in a distance of two times antenna dimension squared divided by wavelangth, the wave can be approximated by a spherical TEM-wave with orthogonal E- and H-field | |
FDDTwo channels, one for uplink, one for downlink used in
parallel | ||
Field strengthSize of a vector field e.g. in volts per meter, V/m, for an electric field E | |
Field strength patternPattern of the field-strength, proportional to the square of the field strength pattern | ||
Figure of meritQuantity used to characterize the performance of a device, system or method, relative to its alternatives | |
Forward Error CorrectionThe
message is encoded so that the receiver can detect and correct (some) errors
without retransmission | ||
Fourier spectrumSpectrum caused by Fourier transform | |
