  2. Resolution to Comment to #15 • Comment #15 • How to deal with line spectra in the center frequency in case of SC-OOK mode? . • Waiting on a number for the carrier leakage. • Resolution • Maximum line spectra in the carrier frequency is limited to less than 35 dB in case of 1 MHz RBW. • Add text “SC-OOK shall meet the same PSD mask as SC, except the single line spectra at the carrier frequency.”

  3. Carrier leakage in OOK 40 20 25dB 35dB 0 -20 -40 PSD (dB) -60 Approximate value of line spectra Linespectra (dB) = 10log(OBW/RBW) OBW: Occupied Bandwidth RBW: Resolution Band Width -80 -100 RRC PA OBO=3dB, RBW=1MHz -120 PSD mask for SC -140 -5 -4 -3 -2 -1 0 1 2 3 4 5 Frequency (Hz) 9 x 10

  4. Resolution to Comment to #113 • Comment #113 • OOK provides no befit when mask compliances is required at the transmit and operation with devices at neighboring channels is needed • Resolution • OOK has benefits for low power consumption, low complexity, lowest cost portable applications even when mask compliances is required. • Add text “SC-OOK shall meet the same PSD mask as SC, except the single line spectra at the carrier frequency" March, 2008 Slide 4
