Hello teachers: I'm a graduate student. I would like to ask how to change the antenna's one-receiver to one-receiver-two-receiver or two-receiver-two-receiver? The boards used are zedboard and ad9361s2.  Thank you!

there are 2 tx and 2 rx. For 2 rx: https://github.com/open-sdr/openwifi/blob/master/doc/app_notes/iq_2ant.md For 2 tx: https://github.com/open-sdr/openwifi/tree/master/doc tx_intf reg_idx 16:

16 | tx antenna selection and cdd control | bit1: 0 or 1 to select ant0 or 1. bit4: 1 to enable simple cdd (two antennas have 1 sample tx delay) -- | -- | --
