Hi Ihab,
1) Frequency range: 1.5 - 38 GHz since the B205 mini only goes up to 6 GHz, you're bound to use an
external mixer. The device you chose for that will completely
depend on your specific application's needs. Also note that
finding something that works as well at 1.5 GHz as it does on 38
GHz is probably pretty expensive, so and finding antennas that
work across that range isn't trivial, either. So I'd recommend
that, at least for a first prototype, you restrict yourself to a
smaller frequency range. If you stay below 6GHz, the B205 can do
that on its own 2) Bandwidth range : 2 - 56 MHzThe B205 mini can definitely dot 56 MHz of bandwidth; the question is whether your PC can process them fast enough and whether your USB3 controller can sustain these rates. 3) Modulation : Qpsk - 256 QAMWell, that's just a question of software that you'll write :) 4) Data rate range : 150Mbit/s - 326Mbit/s.That sounds doable, considering the only limit here is Shannon's channel capacity and your ability to write good software including synchronizers, equalizers, channel codes etc. 5) Error correction method : i thinks it is FEC.Most definitely you'd want some channel coding.
