Abstract:
1. An interference mitigation system for improving isolation between transmitters and receivers in wireless communications systems comprising: a transmitter that transmits a transmit signal during a first time slot while a switch is in a first position; a feedback coupler that generates a feedback signal based on the transmit signal, wherein a characteristic of the feedback signal is representative of a characteristic of the transmit signal, an interference cancellation unit that processes the feedback signal to generate a processed signal; a receiver that receives an intake signal during a second time slot while the switch is in a second position, wherein the intake signal includes a first component from a signal received by the receiver and a second component from interference from the transmit signal, wherein whether the switch is in the first position or the second position is based on a time-division multiplexing technique; and a combiner that combines the intake signal received with the processed signal to generate a combined signal.
