Fig. 5-11: WCDMA PRACH: UE Power vs Chip
●
UE Power
The bar graph covers up to 5 preambles and displays the mean power of each pre-
amble, calculated as the average of the power of all samples in the preamble,
excluding a 25 µs guard period at the beginning and end of the preamble.
●
UE Power vs Chip
The diagram covers all 4096 chips of the "Preselected Preamble", labeled 0 to
4095. Additionally the diagram shows the power for 2560 chips before and after the
last evaluated preamble. These results are labeled -2560 to -1 and 4096 to 6655.
●
Power Steps
For each preamble the bar graph displays the UE power difference to the previous
preamble. For the first preamble there is no power step result.
