Definition at line 99 of file satellite-fading-external-input-trace.h.
Referenced by GetFading().
◆ m_startTime
|
private |
Fading start time and interval calculated from the actual trace file.
Note, that the current implementation assumes that we have constant time interval between fading samples. This assumption has been made for speed-up issues.

◆ m_traceFileType
|
private |
There may be different fading file types.
- FT_TWO_COLUMN
- First = time in seconds
- Second = fading in dB
- FT_THREE_COLUMN
- First = time in seconds
- Second = fading in dB
- Third = scintillation in dB
