Patent ID: 6859506

Claim:
An ultra wideband receiver that suppresses self-noise, comprising: a first mixer having a first input, a second input and an output; a second mixer having a first input coupled to the output of the first mixer, a second input and an output; a codeword generator configured to generate an n-bit non-return-to-zero codeword having a same predetermined sequence of bits as an encoding codeword used to encode a transmitted data stream and invert a predetermined number of bits of the n-bit non-return-to-zero codeword; and a wavelet generator having an output coupled to the second input of the second mixer and configured to output a sequence of ultra wideband wavelets having a predetermined shape, wherein ultra wideband wavelets received via an antenna coupled to the first input of the first mixer, the wavelets having encoded therein the transmitted data stream encoded with the n-bit non-return-to-zero codeword, the n-bit non-return-to-zero codeword is input to the second input of the first mixer, and the output of the second mixer is a detection waveform having decoded therein the transmitted data stream.
