[Discuss-gnuradio] Mixer Frequency of RFX900

Hi, All, Kind of confusing about the IF of RFX900. According to what Eric said ( http://lists.gnu.org/archive/html/discuss-gnuradio/2010-06/msg00113.html) the RFX boards directly converts UHF to baseband signal. Can it be understood as usrp.tune(f,...) sets the mixer frequency in the RFX board to

[Discuss-gnuradio] Signal Seperation

Hi, Could somebody give me some tips and help on the following problem? Really appreciated! The input signal is b1(t)*sin(f1*t) + b2(t)*sin(f2*t), where f1 and f2 are close but different, and b1(t) and b2(t) are two different square waves with different period. After the USRP down coverts this w

[Discuss-gnuradio] Inband signaling and m-blocks for Frequency Hopping

Hi, All, In my current design, frequency hopping is designed to happen over 32MHz bandwidth, as fast as possible. (although I admit that by using USRP1, it may not be that fast as I expected). However, I am not very clear about how to do so. I checked the implementation of bluetooth (gr-bluetooth
