I want to know what is the signal coming from the USRP onto the USB bus.
know that the received signal is a baseband signal and assuming complex
sampling (I have RFX2400 daughterboards) each complex sample that enters
USB bus is the following,
x[i] = (inphase_component) + j (quadrature_component), and
x[i] = m(t)cos( 2piFREQ_OFFSETt + PHI ) + jm(t)sin(
PHI ), where m(t), is the actual message signal, FREQ_OFFSET is the
frequency offset, and PHI is the phase.
Is that correct?
