Patent ID: 7394866

Claim:
A system for suppressing self-noise in an ultra wideband wavelet transmitter, comprising: an exclusive OR circuit having a first input configured to receive data, a second input configured to receive a whitening sequence from a noise source, and an output; a first differential mixer having a first port, a second port and an output, said second port being a differential input port having a first differential input and a second differential input, said first port being coupled to the output of the exclusive OR circuit; a second mixer having a first input, a second input and an output, said output of said first differential mixer being coupled to the first input of said second mixer; a pulse generator configured to generate at least two pulse streams; wherein: one of said at least two pulse streams is input to the first differential input of said first differential mixer, and a different one of said at least two pulse streams is input to the second differential input of said first differential mixer, said whitening sequence is input to the second input of said second mixer, and said output of said second mixer provides an ultra wideband sequence of wavelets modulated in accord with the data, for transmission.
