Anyone see any good technical papers on 1XDV

Clark,
There are 3 proposals for dv foundation technology presently being cross tested and verified by competing teams...
L3NQS (LU, LG Electronics, LSI, NT, QCOM, Samsung)
1xtreme (MOT, TI, Philips, Altera, NOK)
LAS-2000 (CWTS [China], LinkAir)
also, Tantivity is involved with what will, in all probability, become component proposals or technology merged with another proposal....

LAS-2000 response to the dv Decision Criteria Matrix:

The CWTS and LinkAir appear to submit their LAS-CDMA spreading and coding scheme (which is the heart of their proposal - and in reviewing their responses to the Decision Criteria Matrix, perhaps the only meaningful difference between it and cdma2000) as a component proposal as well - in that they hope, on the contingency that they're not chosen as foundation technology (which appears increasingly likely), to integrate it with the winning foundation technology as a component technology....

Here is a dated (3/26/01) comparison by NOK of differences and similarities between primarily what was then L'QS and 1xtreme proposals .... (perhaps bear in mind the ?? credibility of the source <g>)... Around this time the 1xtreme team was hinting at merging proposals with what was then L'QS. The "iFLEX" noted was NT's proposal before merging with what was by that time L3QS to form L3NQS.
