I am using the IQ values collected from the Channel Sounding example. The data in the 0 section seems to indicate that this channel is not in use? For example, as shown in the picture, the three IQ data in the middle are all 0. So, is the frequency of the channels before and after these three data values 4 MHz different?

Hi,

The person who has more knowledge on the channel sounding is away today and hopefully be back tomorrow. 

But I can give you some response to your question.

For example, as shown in the picture, the three IQ data in the middle are all 0. So, is the frequency of the channels before and after these three data values 4 MHz different?

The zeros are empty T_PM measurements, not real IQ at a valid tone. The The mid-array zeros does not seem to be real 0-amplitude channels, they seem to be placeholders where no phase sample was taken.

The channel spacing frequency before and after these three 0 data points is 4 MHz?
