Encoding and decoding of information for wireless transmission using multi-antenna transceivers

One or more non-transitory machine-readable media storing instructions that, when executed, cause one or more processors to perform operations to communicate using multiple transmit antennas and multiple receive antennas over a multi-input-multi-output (MIMO) communication channel, the operations comprising:

• receiving, using a plurality of receive antennas of the multiple receive antennas, a plurality of first radio frequency (RF) signals over the MIMO communication channel, the plurality of first RF signals corresponding to first information transmitted from a source device over the MIMO communication channel;
• processing the plurality of first RF signals using at least one first machine-learning network to generate second information as a reconstruction of the first information having been altered by transmission through the MIMO communication channel;
• estimating, using the second information, channel state information (CSI) corresponding to the MIMO communication channel, the CSI indicating at least one of
• a state of the MIMO communication channel,
• spatial information corresponding to the multiple receive antennas, or
• scheduling information corresponding to multiple users of the MIMO communication channel;
• and
• processing, using the estimated CSI, a plurality of second RF signals for transmission over the MIMO communication channel using a plurality of transmit antennas of the multiple transmit antennas.
