MIMO synchronization requires the following fundamental inputs.
device names—The unique IP address of each
being controlled. The default IP address for new
IQ rate—The sample rate of the baseband in-phase/quadrature (I/Q) waveform determines the real time bandwidth being acquired or synthesized.
carrier frequency—The mid-point in the spectrum you are analyzing. The carrier frequency becomes the center or DC component when converted to baseband I/Q.
gain—Adjustable gain, typically
30 dB, that you apply to the analog RF signal.
active antenna—Switch setting that determines which RX or TX SMA port to use for acquisition or transmission.
number of samples—The number of samples to acquire or transmit from the device. Each driver should call either
niUSRP Fetch RX Data
niUSRP Write TX Data.
Your block diagram should look similar to the following figure.
