  2. Statistics of the Largest MPC • Sample frequency: 8 GHz • TG15.4a CM1 through CM9 • 500 MHz wide bandwidth Across all channels Shahriar Emami, Freescale Semiconductor

  3. Statistics of the Largest MPC • Sample frequency: 2 GHz • TG15.4a CM1 through CM9 • 500 MHz wide bandwidth Across all channels Shahriar Emami, Freescale Semiconductor

  4. Statistics of the Largest MPC • Sample frequency: 500 MHz • TG15.4a CM1 through CM9 • 500 MHz wide bandwidth Across all channels Shahriar Emami, Freescale Semiconductor

  5. Summary • The ratio of largest multipath component to the total CIR energy for all TG4a channels were calculated. • The statistics for individual environments and across all channels were obtained. • Mean and minimum of the largest multipath component contribution in TG4a channels are -16 dB and -23 dB, respectively (if the sample frequency is 8 GHz). • Mean and minimum of the largest multipath component contribution in TG4a channels are -10 dB and -17 dB, respectively (if the sample frequency is 2 GHz). • Mean and minimum of the largest multipath component contribution in TG4a channels are -8 dB and -13 dB, respectively (if the sample frequency is 500 MHz).
