Hi, I came across a very beautiful gnuradio/USRP usage for intentional signal aliasing application. The authors used USRP2 with its 25MHz digitizing capability to analyze the full bluetooth 79MHz wide channels by removing the RFX2400 anti-aliasing filter and disabling the FPGA HBF when working with decimation of 4. http://www.shmoocon.org/presentations-all.html#bluetooth www.ossmann.com/shmoo-09/ossmann-spill-shmoo-2009.pdf http://sourceforge.net/projects/gr-bluetooth/ The source code contains a good documented readme files that explains gnuradio/usrp modifications needed.
