If iwr 1642 is set to transmit signals for two antennas in mmwave studio, how is chirp reused? Is BPM-MIMO or TDM-MIMO?

    Hello,

    Transmitting the signals from the two antennas are dependent on the way you would configure in the "Chirp configuration" Under "sensor configuration" tab. If you assign for both TX to the given Chirp config (section in the mmWave studio) then it would be transmitted simultaneous two transmitters together. Or you could assign individual transmitters for different chirp config and in the frame configuration if you use the alternate chirp configuration then you would transmit in TDM-MIMO manner. For BPM-MIMO each chirp need to be configured for the BPM bits in the BPM tab.

    Thanks and regards,
