Abstract
An Ultra Wide Band (UWB) transmitting and receiving device that includes a Digital Signal Processor (DSP) for implementing a DC offset cancellation algorithm, an adder for adding a baseband transmission signal from the transmitter and a calibration signal produced by the algorithm of the DSP, a modulator for modulating the signal from the adder, a transmitter amplifier for amplifying the modulated signal, a coupler for applying the output of the transmitter to the receiver, and a switch for selectively connecting the output of the coupler to the input of the receiver.
