Hi!
I am trying to implement an UMTS uplink scanner with GRC. My purpose
is to detect the activity of channels by sensing the spectrum and
comparing the measured power against a certain threshold. The blocks
that I am using are:
uhd_usrp_source--->root raised cosine filter-------power
squelch------rms--------log10-------filesink
So far I am just attempting to calculate rssi values on a specific
channel, and save them into a file using the above chain. but the file
that is created after the whole chain is unreadable in Matlab or Octave.
There must be something wrong in the chain of blocks, but I cannot see
it. Any comments are welcome!
Br,

The files are stored in native complex-float format. Someone posted a
macro about a week ago on the list to deal with this for
Matlab.
