Equation (1) denotes the holographic intensity pattern of the imaged object, in which [E.sub.s](x,y) is the scattered field from the object while [E.sub.r](x,y) is the introduced coherent reference signal.
As shown in Figure 2, while the sum of the first and second components in Equation (3) are placed in the center of the spectrum due to their scalar-only DC structure, the third and fourth components are shifted towards the edges of the PWS due to the convolution of the scattered field with the introduced coherent reference signal in the frequency domain.
This growth is exposing two key weaknesses: 1) inadequate semantics for how to link disparate information together that recognizes inherently different contexts and viewpoints; and 2) a lack of
coherent reference concepts by which to aggregate and organize this linkable content.
Feed forward control is where a
coherent reference noise input is sensed before it propagates past the canceling speaker.
The Commission and ESA are due to propose, a comprehensive European Space Programme in early 2005, which is meant to act as a
coherent reference agenda for Europe's efforts in the space sector.
But metafiction can be usefully defined in terms of fundamental mechanisms that thwart the reader's application of world knowledge, preventing the construction of a coherent reference world.
Denied authority, the authorial audience cannot employ text-external knowledge to sort out the confusion of the provisional fictional world or to build a coherent reference world.
By averaging the two identical parts of the long training symbol,
coherent references can be obtained with a noise level that is 3 dB lower than the noise level of data symbols.
