CANCELLATION SIGNAL GENERATION FOR MULTIPLE INPUT AND MULTIPLE OUTPUT (MIMO) ANALOG INTERFERENCE CANCELLATION

摘要

A multiple input and multiple output device includes a first input switch, a second input switch, a first set of analog interference cancellation (AIC) circuits, and a second set of AIC circuits. The first input switch is configured to select one of a first transmit input of first transmit inputs or a first transmit input of second transmit inputs. The second input switch is configured to select one of a second transmit input of the first transmit inputs or a second transmit input of the second transmit inputs. The first set of AIC circuits and the second set of AIC circuits are coupled to the first input switch and to the second input switch. The first set of AIC circuits is configured to output a first cancellation signal. The second set of AIC circuits is configured to output a second cancellation signal.
