The introduction of the linear carrier function, φ(x, y) = αx + βy, shifts the terms E(u, v) and E*(u, v) in opposite directions in the frequency spectrum as can be seen noting that: E(u,v)=F{12b(x,y)eiϕ(x,y)},E(u,v)=F{12b(x,y)eiϕ(x,y)},...

If you are in the USA, you might recognize HD Radio (aka NRSC-5) signals as the rectangular looking bars on the frequency spectrum that surround common broadcast FM radio signals. These signals only exist in the USA and they carry digital audio data which can be received by special HD Rad...
The frequency characteristic of the filters is discussed in terms of this transfer function. Two-dimensional LPSV filters are designed based on the one-dimensional Parks-McClellan algorithm. The resultant LPSV filters divide the input spectrum into some components that are permuted and possibly ...
The methods for spreading the bandwidth of the spread-spectrum transmission are (1) frequency-hopping spread spectrum (FHSS), (2) direct sequence spread spectrum (DSSS), (3) pulsed-frequency modulation or chirp modulation, and (4) time-hopping spread spectrum. The last two types are not allow...
The general concepts set forth herein may realize several substantial benefits that were not previously possible. Ad purchases, for example, can be monitored and improved for very greatly enhanced reach and frequency of viewed ads. Rather than continuing to present the same to a viewer who has al...
