Change History
comment:1 Changed 2 years ago by jean-philippe
- Effort Required set to Unknown
- Milestone changed from 3.2.0 to 3.2.0 Beta 19
comment:2 Changed 2 years ago by jean-philippe
- Milestone changed from 3.2.0 Beta 19 to Need feedback from STG
comment:3 Changed 2 years ago by jean-philippe
These values are presented only for display just for information. No decision in STG21 21 on this tickets. This need further consideration.
comment:4 Changed 20 months ago by jean-philippe
STG23 decided to add 2 extra columns in the simulation sumary:
- Mean and stdDev derived from linear values (bold)
- Mean and stdDev derived from dBm values (on the right hand side)
And add a note in the handbook explaining why the dBm calculation is kept (i.e. to enable backward version results comparison)
Target: 3.2.3 release (to check with developer how long it take)

Implemented for the simulation summary in rev. [845]

Text bold and swapped dBm and linear panels [846]

dRSS linear and dRSS dBm was swapped [850]

[860] was also a fixe for this ticket. The description of the commit is for another ticket.
comment:12 Changed 19 months ago by jean-philippe
[851] is also a fix to this ticket.
comment:13 Changed 19 months ago by thomas.thorndahl
Partly reverted to original display of linear mean and stddev in [861] as agreed.
comment:14 Changed 19 months ago by jean-philippe
during the implementation, it was found out that the mean value derived from linear calculation exhibit high fluctuation, while the mean value derived from dBm remain constant.
The calculation are correct but displaying such information as originally agreed by STG is not very usefull.
After discussion with Karl loew, it is proposed to replace the mean (linear) in the display by the median (linear). The difference is negligible between the median derived from the dBm or linear values. These values are also very close to the mean derived from the dBm values.
STG was requested to provide feedback. no response received. silence is approval.
the median(linear) will be proposed for revision in the next beta release.

fix made in [863]
comment:17 Changed 19 months ago by thomas.thorndahl
Implemented median display for drss/irss-signaldisplays [864]

- Status changed from new to closed
- Resolution set to Fixed
tested with matlab. ticket is closed.
there is a need for further specification on this. For instance, on the display of the results. Should we show all the results or do we have a switch to select what is to be shown?
need STG feedback.
