According to the embodiment discloses a method providing direct RF sampling of the received signal in a full duplex system. A sampler in the full-duplex system comprises a buffer to clip an amplitude information from each of a coupled transmitter (Tx) signal and a voltage at an antenna port of the sampler for obtaining a buffered transmitter signal and a buffered voltage at the antenna port. Phase detector in the sampler is configured to perform sampling of time delay between the buffered transmitter signal and the voltage at the antenna port and generate an output. The sampler further comprises current integrator configured to pass the output of the phase detector for generating a sampled output, wherein the sampled output generates an output received signal.

Sampler in a full-duplex system and method of sampling received signal

Embodiments herein provide a transceiver system-for full-duplex communication. The transceiver system-includes an electrical balance based duplexer (EBD)coupled with at least one transceiverandand at least one antennaand. The at least one antennaandis configured to transmit first signals and the at least one antennasandis configured to receive second signals using at least one circulators. The EBDis 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.
