Probably available in English if you care to look.
Yeah, I cared to look. I couldn't find it on any English-language web site. I have no intention of spending all day looking, though, and that's why I couched my statements so that anyone who read between the lines could easily see that I never intended to speak authoritatively. This is what Ilmarinen calls "intellectual dishonesty." I call it giving appropriate notice that a non-techie is speaking, that the search is incomplete, and that the reader should be aware of the limits.
Why is error-correction important in data transfer? Seems that if Nokia thinks it is important, perhaps the chances are very good that it is significant. If Tiger Woods tells me I need to make a change in my grip, I listen. I may not know the technical details, and I do rely a lot on my intuition, but assure you that I do know to listen when the appropriately qualified talk about it. From your translation: "With speech transmissions (thus when normal telephoning) it is already used since beginning of the GSM standard 13 kBit/s which can be explained thereby that the human ear does not register small errors, these [errors] during data communication is [sic] however inexcusable."
If errors are inexcusable to Nokia, that's good enough for me. My intuition seems to be on the right track here even though I admittedly did not know of Nokia's error correction scheme when I originally posted on the subject. Can you provide a date for when the German Nokia statement was made? I see no error correction information dated before October, 2000, but, as I have said before, my search is not exhaustive.
Let's see. GSM transmits data at 9.6 kbps. Error-corrected HSCSD supposedly is at a speedy 14.4. Interesting to determine whether that on both uplink and downlink. Doesn't really say, would be interesting to know. It would also be interesting to know why the error correction scheme was implemented. If error correction is not so big a deal, as I think you suggest, why did Nokia apparently slow down HSCSD's speed to incorporate it?
The response to it gives the new channel coding, with which 14.4 kBit/s for the actual data and only the remainder for the error correction bits are used.
That's just excellent.-vbg- Spend more money on software upgrades to crank up [corrected] GSM's data rate all of 5kbps. Gotta do something while GPRSux flounders, EDGE bleeds, both are looking for handsets, the UMTS standard makers take their month-long vacation, etc., etc.
You think Illmarinen is a class citizen of this board? Accepts apologies gracefully? You need to look at this:
Carranza, why are you pimping??
