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 spacing is 0.125 ns).
• Mean and minimum of the largest multipath component
contribution in TG4a channels are -10 dB and -17 dB,
respectively (if the sample spacing is 0.50 ns).
