I have recorded the data of a signal using an SDR to a file (binary I and Q data), using GNUradio. I would like to extract from the recorded data the power of the CW as a function of time, preferably in logarithmic scale, i.e. X-axis- time from the beginning of the file or PC time of the data, and on Y-axis the power in dBm in a certain frequency.
I can use either MATLAB or GNUradio for this purpose.
Appreciate the help.
