I took the channel impulse response (CIR), generated by the preamble and I have some questions about it.
Attached is the figure of the absolute value of the CIR.
- What is the blank space in the CIR? Is this some sort of reset? Or did I miss some values?
- Which unit does the figure actually have?
- Is there some way to get the noise level from this plot. I understand that due to the accumulation the noise gets less, therefore it seems not so straightforward. Or is there any other way to get the noise level? I know that the DW1000 model offered the possibility to read the noise level. Is there something similar for the DW3000 and if not, why so?
