Cheers, Jake ---------- Forwarded message ---------- Date: Mon, 5 Apr 1999 18:19:25 -0400 Dear Colleague: In recent weeks we designed sequences of low-density parity check codes that provably perform at rates extremely close to the Shannon capacity. For instance, our best code of rate 1/2 is asymptotically less than 0.06dB away from capacity for the AWGN channel. Simulation results indicate that for a length of 1,000,000 we can achieve an error probability of 10^(-6) at 0.13dB from capacity. Our codes are built from highly irregular bipartite graphs with carefully chosen degree patterns on both sides, by optimizing the threshold obtained in our previous paper. Moreover, the paper gives some more theoretical insight into the behavior of the decoding process. A preprint of our paper, entitled "Design of provably good low-density parity check codes" can be obtained at http://cm.bell-labs.com/who/{ruediger or tjr}/pub.html As always, comments are most welcome.

All of which is a pity, because actually he has a point. In this modern world, with upcoming SGML derivatives such as DocBook, XML etc (and even with LaTeX), it is possible - automatically - to produce HTML as well as postscript output. There really is no reason not to produce an HTML version of a LaTeX/DocBook/XML academic paper as well as the 'normal' postscript version. I too, even though I have postscript/pdf viewers and printers, find it moderately tedious to have to download a file, probably unzip it, run it into gs (or let netscape do all that) simply to see from the table of contents whether it is interesting or not. But having said that, if I require a hardcopy, then the postscript or pdf version will always produce a better result AND on fewer pages (save our trees, plant some more!). Dirk Koopman G1TLH PS with regard to your comments on the GPL, the correct word is 'change' not 'destroy' - but I do understand that to some, especially in the context of the word 'business', the two terms are equivalent.

Hell, most of the programmers on GPL projects are "legimate software programmers" for their day jobs. Also, many have been lulled by their contempt for Microsoft into supporting an agenda which hurts Microsoft's competitors more than Microsoft itself! The GPL forecloses markets which Microsoft's current potential competitors might have entered. It poisons the well, so to speak. >Adobe Acrobat is highly overpriced, and if anything they forced a free alternative to be created. The subject of the discussion was PostScript. However, I would rather have seen PostScript die due to overpricing (which is the natural order of things when someone charges too much for a product) than have it preserved, zombie-like, by the GPL. >God, what rock did you crawl out of!

The same is not true of the GPL. The GPL is an active attempt to destroy businesses. > I guess TAPR should charge large amounts for the code done for the SS projects > as well? The problem is not whether there is a charge. The problem is whether the goal is to destroy the market. The purpose of the GPL is, again, to destroy for-profit companies, against which the author harbors a grudge. > Or is it okay with you do have some things done out of love and not greed?!? The GPL was done out of spite, with intentional malice toward programmers seeking to earn a living. Perversely, it attempts to turn their efforts AGAINST their own interests, and too many have fallen for the propaganda surrounding the GPL and fall into that trap. I realize that many do not realize this, but this is its well-documented history.

The location was a forest south of Perth, Australia. The attenuation of the forest was about 10 dB/100 feet (or 30 meters for the English challenged). This was not a precise measurement, but seemd to be close and consistent. The forest consisted of leafy trees, not pines (OK, dudaceous -- or however you spell it -- not coniferous). The radios were prototypes we built around the Harris PRISM chipset, which has its own limitations. The data was being sent at 1 Mbps, DPSK. Here in the desert with the same setup, we obtained ranges comparable to your 16 km/10 mile. We also noted in Australia that rainfall had no discernable effect. (We timed the trip to be in the rainy season.) Not to say there is zero addiitonal attenuation, just that we were not able to see any differences in range performance or measuered signal strengths.

Your observations seem to agree well with predictions in the literature. The CCIR (now ITU-R) estimate for attenuation from trees at 2.4 GHz is around 0.35 dB/m, or very close to 10 dB for 30 m (BTW, the predicted loss at 915 MHz would be about 4 dB less). Also, rain (and snow, fog, etc) is said to have little effect on path loss at 2.4 GHz and below. I'm planning to measure the actual path loss on my tree-obstructed path, and I'll report the results here. It won't be until after the annual Dayton madness next weekend, though.

We have a large lowland forest round where we live called Thetford Forest (reputed to be the largest such in Western Europe), many leisure activities (as well as the occasion emergency) requiring radio assistance take place in this forest every year. Empirically it has been found that low power (<=5w) 2m will penetrate the "green sponge" (as it is known round hereabouts) even when wet, 70cms will not (or at least, not very far - even in the dry). Another thing that has been deployed around the forest is 1800Mhz GSM mobile telephone systems, these too are noticably attenuated by the forest and made completely useless by wet forest.

While the losses due to trees probably are higher at 70 cm than 2m, that's not the whole story. Don't forget that you also have to account for the decreased effective aperture of the antennas at the higher frequency. Assuming that you're trying to communicate between handhelds that have the same power output and quarter-wave whips on each band, the 70 cm receivers will have nearly 10 dB less power delivered to their inputs than the 2 m receivers will, on a line-of-sight path. You could use higher-gain omni antennas on the 70 cm units to overcome this disadvantage, but this makes them finicky for positioning due to the narrow vertical beamwidth. It's easy to overcome this problem on fixed links with higher-gain directional antennas, though. > Another thing that has been deployed around the forest is 1800Mhz GSM mobile > telephone systems, these too are noticably attenuated by the forest and made > completely useless by wet forest. Yep, this is certainly a disadvantage of the upward push to find available spectrum for mobile communications - too bad the TV broadcasters have most of the best spectrum for mobile locked up!

Well, they could be using some exotic multi-level modulation scheme (like 256QAM) to get more bps/Hz before spreading. But in this case, I think the answer is simpler: it's vaporhardware. From what I've heard, Inficom sells franchises rather than hardware.

After several dozen e-mails and calls to the number posted on their web page, I finally had someone from Inficom call me. I asked him several times how the system worked and he kept telling me that I wouldn't understand it. I asked how the equipment could defy basic rules of RF propagation and again was told that I couldn't possibly understand how they did it because I wouldn't stop thinking in normal terms. I asked to stay on their mailing lists so that I'd have some interesting jokes to send around to fellow engineers once in a while.
