Abstract
Embodiments herein provide a transceiver system 1000a-1000f for full-duplex communication. The transceiver system 1000a-1000f includes an electrical balance based duplexer (EBD) 100 coupled with at least one transceiver 200a and 200b and at least one antenna 300a and 300b. The at least one antenna 300a and 300b is configured to transmit first signals and the at least one antennas 300a and 300b is configured to receive second signals using at least one circulators. The EBD 100 is configured to provide an isolation between the transmitting signals and the receiving signals in a same channel full duplex (SCFD) front-end circuit using the at least one circulators.
Claims13
A transceiver system for full-duplex communication, comprising:
- an electrical balance based duplexer (EBD) coupled with at least one transceiver and at least one antenna antennas, wherein the EBD 100 comprises a plurality of ports;
- the at least one antenna configured to transmit first signals;
- the at least one antenna configured to receive second signals using at least one circulator;
- wherein the is configured to provide an isolation between the transmitting signals and the receiving signals in a same channel full duplex (SCFD) front-end circuit using the at least one circulator by:
- passing transmitting signals and the receiving signals at a first port from the plurality of ports and at a second port from the plurality of ports through the at least one circulator;
- equally dividing the transmitting signals and transmitting the divided signals through the at least one antenna;
- receiving a portion of the divided transmitting signals transmitted from a first antenna from the at least one antenna and a second antenna from the at least one antenna;
- and
- matching input impedance to provide wide-band isolation between two Tx/Rx pairs under balanced condition between the transmitting signals and the receiving signals in the SCFD front-end circuit using the at least one circulator.
A method for interference cancellation in full-duplex communication, comprising:
- detecting, by an electrical balance based duplexer (EBD) transmitting signals from at least one antenna;
- detecting, by the EBD, receiving signals from the at least one antenna;
- and
- providing, by the EBD, an isolation between the transmitting signals and the receiving signals in a same channel full duplex (SCFD) front-end circuit using at least one circulator by:
- passing transmitting signals and the receiving signals at a first port from the plurality of port and at a second port from the plurality of ports through the at least one circulator;
- equally dividing the transmitting signals and transmitting the divided transmitting signals through the at least one antenna;
- receiving a portion of the divided transmitting signals transmitted from a first antenna of the at least one antennas and a second antenna from the at least antenna;
- and
- matching input impedance to provide wide-band isolation between Tx/Rx pairs under balanced condition between the transmitting signals and the receiving signals in the SCFD front-end circuit using the at least one circulator.
