June, 2005 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). Shahriar Emami, Freescale Semiconductor
