Abstract:
Same-channel full-duplex communications can be adapted for multiple-input multiple-output (MIMO) processing in order to derive increased signal performance through the exploitation of spatial diversity. Strong interference components from transmissions over multiple local antennas can be removed from a received radio signal to allow array and diversity gain benefits of MIMO to be enjoyed in same-channel full-duplex communications. More specifically, baseband samples of two or more MIMO transmission signals may be used to perform channel estimation on a received radio signal by correlating the baseband signals with the radio signal to estimate interference channels associated with the MIMO transmission signals. The estimated interference channels are used to subtract corresponding interference components from the received radio signals.

Claim (Index 1):
A method for receiving data in a multiple-input multiple-output (MIMO) full-duplex communication channel, the method comprising:\n receiving, by a device, a radio signal over a first antenna of a multi-antenna array, the radio signal including a received signal component corresponding to a communications signal being received over the MIMO full-duplex communication channel; obtaining baseband samples of transmission signals communicated over the MIMO full-duplex communication channel, the transmission signals including at least a first transmission signal emitted over the first antenna and a second transmission signal emitted over a second antenna of the multi-antenna array; performing channel estimation for the radio signal in accordance with the baseband samples to generate an interference-cancellation signal, the interference-cancellation signal including at least a first interference component corresponding to the first transmission signal and a second interference component corresponding to the second transmission signal; and subtracting the interference cancellation signal from the radio signal to at least partially isolate the received signal component from interference in the radio signal.
