Abstract:
1. An interference mitigation system for improving isolation between transmitters and receivers in wireless communications systems comprising: a power amplifier that amplifies a transmit signal that is transmitted by the system; a feedback coupler that generates a feedback signal based on the amplified transmit signal, wherein the feedback signal is representative of an interference characteristic attributed to the amplified transmit signal, an interference cancellation unit that: a combiner that combines an intake signal received from a receiver and the processed signal to generate a combined signal, wherein the intake signal includes a first component from a signal and a second component from interference from the transmit signal; and a switch that changes its position from a first position to a second position at times corresponding to a time-division duplexing technique, wherein the intake signal is combined with the processed signal while the switch is in the second position.
