An impulse radio transceiver for full duplex ultrawide-band communications. The transceiver comprises an impulse radio transmitter that transmits impulse radio signal pulses, an impulse radio receiver that receives impulse radio signal pulses. Either or both of the impulse radio transmitter and the impulse radio receiver synchronizes the transmission and the reception of the impulse radio signal pulses for the pulse interleaved communications. Pulse interleaving avoids self-interference between the transmitted impulse radio signal pulses and the received impulse radio signal pulses. In addition to pulse interleaved communications, bursts of pulses can be transmitted between two transceiver in an interleaved fashion. Alternatively, two different pulse repetition rates are used to transmit and receive impulse impulse radio signal pulses simultaneously. Still further, selected pulses of the received or transmitted impulse radio signal pulses are blanked to avoid interference.
