I came across a very beautiful gnuradio/USRP usage for intentional
aliasing application. The authors used USRP2 with its 25MHz digitizing
capability to analyze the full bluetooth 79MHz wide channels by removing
RFX2400 anti-aliasing filter and disabling the FPGA HBF when working
decimation of 4.
The source code contains a good documented readme files that explains
gnuradio/usrp modifications needed.
