Delay Doppler (Channel Sounding)
Channel Sounding has the ability to create Delay Doppler Maps from Channel Impulse Responses (CIRs). For it to function properly, the CIRs must be transmitted periodically, and the user must know the period at which the CIRs are transmitted. The user can use either Non-Segmented Capture mode or Fixed Length Segmented Capture mode.
These are the parameters related to Delay Doppler functionality:
Determining the Impulse Response Period
The following is an example of how you might determine the Impulse Response Period based on known parameters:
Symbol Rate = 1 GHz Gigahertz: A frequency measurement which equals one billion hertz., Sequence Length = 128
CIR Transmission Period = 8 * 128 / 1 GHz = 8.192 us
Segment Trigger Period = 10 * CIR Repetition Period = 81.92 us
→ Set Impulse Response Period = Segment Trigger Period
