Abstract:
A system for enhancing isolation in coexisting time-division duplexed (TDD) transceivers includes: a blocker canceller that transforms a transmit signal of a TDD transceiver into a blocker cancellation signal configured to remove transmit-band interference in a receive signal; a first filter that filters the blocker cancellation signal; a second filter that filters the transmit signal; and a transmit-noise canceller that transforms the filtered transmit signal into a transmit noise cancellation signal configured to remove receive-band interference in the receive signal.

Claim (Index 1):
A system for enhancing isolation in coexisting first and second time-division duplexed (TDD) transceivers:\n a blocker canceller that, in a first operating mode, transforms a transmit signal of the first TDD transceiver into a blocker cancellation signal configured to remove transmit-band interference in a receive signal of the second TDD transceiver; wherein the transmit signal is transmitted in the first frequency band in the first operating mode; wherein the receive signal is received in a second frequency band non-identical to the first frequency band in the first operating mode; a first tunable bandpass filter that, in the first operating mode, filters the blocker cancellation signal to remove noise in the second frequency band generated by the blocker canceller; a second tunable bandpass filter that, in the first operating mode, filters the transmit signal to remove power in the first frequency band; and a transmit-noise canceller that, in the first operating mode transforms the filtered transmit signal into a transmit noise cancellation signal configured to remove receive-band interference in the receive signal of the second TDD transceiver; wherein the system, in the first operating mode, combines the filtered blocker cancellation signal and the transmit-noise cancellation signal with the receive signal of the second TDD transceiver, resulting in generation of a reduced-interference receive signal.
