This is the first time I send email to GNURadio Mailing List. Very glad
to exchange ideas to all members.
Recently, I want to extract RSSI from USRP N210. Is there any system to
extract RSSI,or I have to build system by myself?
In GRC, is there any library that has math module to calculate square
and square root

welcome to the mailing list!
GRC is a tool to construct flow graphs of GNU Radio blocks; there is
no “math library” in GRC, but there are blocks that perform
mathematical operations. Since you are probably looking for
sqrt(|x|), try using the “Complex to Mag” Block.
As a side node, since this topic appears about every two months on
this mailing list: RSSI doesn’t “specify” anything particular. You
will have to have a model for your signal to explain what a received
signal strength is – this is something totally different for
different transmission methods. Therefore, there can never be a single
system to extract RSSI!
