Hello all, Not sure if this belongs here, but I found an old wireless gameboy messager ( http://www.amazon.com/Game-Boy-Advance-Wireless-Messenger/dp/B0002IQOR8 ) and would like to intercept the messages. It uses a CC1020 RF modem in the 915MHz band. The problem is it uses FHSS in a 26Mhz bandwidth. When listening with my USRP I get mostly aliasing noise form out of band hops ( I can only hear 16MHz with the USRP ). I don't think I need to find the hopping code as I can just listen to all channels at once. So my plan is to somehow remove at least one stage of filtering from the FPGA so I can sample at ~4MSPS and have all out of band signals aliased into that bandwidth. My questions is can this be done and is my DSP info correct ( Can this work? ).
Thank you all. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
