doc.: IEEE a TG4a May 15, 2005 Philippe Rouzet (STMicroelectronics)Slide 4 WORKPLAN WEDNESDAY MAY 17th 2005 (1/2) Main items are modulation and PRF. Hereafter is a list of questions related to PRF selection in relation with proposed bandplans and modulations Mandatory PRF « MPRF » –What is the MPRF (on the mandatory sub band)? –What is inside the MPRP (1 pulse, 1 chip) ? Any specificity for preamble? –Relation between MPRF and pulse Peak to peak Voltage –MPRF versus inter pulse interference –Data rate (payload) for MPRF (and which relation between bit /symbol, pulse/chip, and pulse/chip compression 1 ) -reminder : must be demodulated by Non Coherent RX- –…

doc.: IEEE a TG4a May 15, 2005 Philippe Rouzet (STMicroelectronics)Slide 5 WORKPLAN WEDNESDAY MAY 16th 2005 (2/2) PRF/data rate variations –PRF versus maximum data rate (different PRF, or different chip, or different pulse compression?) –Which other PRFs (optional PRFs) ? Same Chip per PRP? –does PRF depend on the subband ( GHz)? –PRF still valid for higher bands (above 6 GHz) ? –… PRF versus Ranging Any foreseen deviation from the ABCD merger chart ?

doc.: IEEE a TG4a May 15, 2005 Philippe Rouzet (STMicroelectronics)Slide 6 UWB PHY Thursday May 18 th (1/2) DISCUSSION ON OPTIONS –Refer to ABCD Mergers Chart –How do we treat options (some can be integrated on the sub groups, others not) –E.g. chirp for TH, Below-one-GHz band, Data rates More on the Simulation –Contributions –Priorities (cf SCD) ORGANIZATION (Pulse Modulation –Phil-, Pulse Compression- Ismael-, Simulation- Saied-) –Schedule, milestones –Drafting (when do we consider IEEE formatting? ), –Conf. Call, process, (pre) decisions –Joint discussions between sub groups, with other groups
