Sessions 1-3
THURSDAY, 13 NOVEMBER 2003
Session 1
Chairman Bob Heile called the session to order at 8:05 a.m.
The chairman announced that the complaint registered yesterday concerning the quotation of a committee member by the press was handled as an example.
The chairman called for contributions and a number of contributors were registered by allotting time in the draft agenda for their presentations.
It was moved and seconded to approve the agenda (document 03/505r2).
- It was moved by Chandros Rypinski and seconded by Ian Gifford to amend the agenda by fixing the time of adjournment at 6:01 p.m. The question was called by a vote of 77 for, 9 against, and 1 abstaining. The motion to amend lost by a vote of 57 for, 64 against, and 1 abstaining.
- It was moved by Roberto Aiello and seconded by Jason Ellis to change the agenda by moving the presentation of contributions to the beginning of the agenda. This motion was approved by a vote of 78 for, 46 against, and 1 abstaining.
- It was moved by Jason Ellis and seconded by Steve Turner to fix the time of adjournment to the time immediately following the contributions immediately preceding the scheduled NO vote discussion and second confirmation vote. This proposed amendment to the agenda lost by a vote of 0 for, 83 against, and 9 abstaining.
- It was moved and seconded to amend the agenda by moving the closing matters to the time immediately following the contribution presentations. This amendment was approved by general consent.
- It was moved and seconded to amend the agenda by fixing the time of adjournment to the time immediately following the closing reports. It was moved and seconded to take the vote on the motion by roll call vote. The motion to take a roll call vote lost by a vote of 47 for, 74 against, and 8 abstaining. The motion to amend the agenda was approved by a vote of 75 for, 52 against, and 3 abstaining.
- The amended agenda was approved on general consent.
The minutes of the previous meeting (document 03/441r3) were approved on general consent.
The first contribution presentation was by Andy Gowans of the UK Radiocommunications Agency (802.18 document 03/046). He reported on efforts in the UK to set emission limits for UWB devices. Matt Welborn agreed to collect feedback from TG3a to give to the UK people.
The second contribution presentation was by Matt Welborn and John McCorkle of XtremeSpectrum (document 03/483r2). The presentation described analysis of interference that may be caused by frequency agile MOFDM, due to the gated nature of the interference as seen by a victim receiver, and discussed how this waveform relates to current FCC rules. Matt also discussed the characterization of interference using amplitude probability distributions (APDs) to indicate the relative frequency of occurrence of high-amplitude interference samples, and conjectured that a change in FCC rules would be needed to accommodate the MOFDM or other hopping signals. John reported on tests that indicate the level of interference caused by gated noise and by gated OFDM signals. Questions from the floor were answered.
The session recessed at 10:36 a.m.
Session 2
Chairman Bob Heile called the session to order at 11:01 a.m.
Questions and answers for the second contribution presentation continued.
The third contribution presentation was by Gadi Shor of Wisair (document 03/506). The presentation offered a critique of reported measurements of the effect of pulsed interference on Fixed Satellite Service receivers, and suggested improved measurement calibration procedures. Questions from the floor were answered.
The session recessed at 12:27 p.m.
Session 3
Chairman Bob Heile called the session to at 1:33 p.m.
The fourth contribution presentation was by Honggang Zhang of CRL (documents 03/457 and 03/472). The presentation described modified UWB pulse shapes for mitigating interference and coexisting with other systems, as well as Japanese contributions on measurements of UWB signals for ITU TG1/8. A small antenna for use with UWB transceivers was also described. Questions from the floor were answered.
The fifth contribution presentation was by Michael McLaughlin of Parthus Ceva (document 03/447). The presentation described techniques for implementing fast FIR filters, including estimates of their complexity in terms of gate counts. Questions from the floor were answered.
The sixth contribution presentation was by Leonard Miller of NIST (document 03/504). The presentation illustrated an analytical technique for predicting the effects of pulsed interference in terms of error probability. Questions from the floor were answered.
The timeline for the TG3a project was reviewed.
The chairman expressed the hope that cooperative efforts will take place during the period between this meeting and the next meeting in January.
The chairman summarized the report to be presented to the WG closing plenary.
Objectives for the January meeting were reviewed.
The meeting adjourned at 3:20 p.m.
