I had recently announced, in sci.astro on 2006.03.12, about my March APS Meeting presentation of a mundane Hubble-like frequency scaling effect arising purely from receiver (sampling) clock variation - just as if the universe was slowing down or speeding up relative to the receiver. This was after multiple favourable reviews in signal processing and radar at IEEE conferences in 2005, since the effect in principle allows the Shannon capacity of any physical channel to be multiplied by a large number. This is to report "successful simulation" of the effect at up to terahertz frequencies and the earth-moon distance scale - see http://www.inspiredresearch.com/sim/Simulator.html for the Java simulator applet. (The applet doesn't always initialize correctly - partly due to applet caching at the browser, but the page explains what values to put in and the knobs to twiddle.) The limit is evidently computational due to the double precision implementation of the Java math library - with quad precision, I believe visible light frequencies and true cosmological scale distances can be similarly simulated. The exercise looks successful in that the only changes from ordinary DFT are exponential sampling and artificial line broadening - neither of which depends on nor supplies the source distance information to explain the clear, distance-proportional scaling of the spectra (do feel free to twiddle - in particular, turn off summing - Sigma - button bottom left and cycle through the source selection - F - at top left - it's fun to literally "Walk the Spectrum" this way!). The core theory is straightforward, as explained at the top of http://www.inspiredresearch.com/simulation.html . The peer-reviewed publication references are given on the site, and a detailed first patent application has been published Jan 12th by the US PTO. At this point, my youngest inspirations, the cosmological redshift and acceleration and an apparent connection to residual instrument creep as also explained on the simulation page, should be less interesting than the broader result that we do seem to have a neat new wave effect to play with and enjoy down here on earth. I'm still exploring ways to rigorously validate physical existence of the effect and would welcome help or pointers for this or towards further development. sincerely, -prasad email: info@inspiredresearch.com
