Patent ID: 7400669

Claim:
A receiver correlator structure comprising: a mixer receiving an ultra wide bandwidth signal comprising a sequence of wavelets of particular shapes and positions, and mixing the ultra wide bandwidth signal with a local ultra wide bandwidth signal comprising a sequence of wavelets of particular shapes and positions correlated to the sequence of wavelets of particular shapes and positions of the received ultra wide bandwidth signal; a bandpass filter, coupled to the mixer output, receiving the mixed ultra wide bandwidth signal, removing the DC components therefrom, and outputting a resultant signal, wherein an initial peak of the resultant signal is proportional to energy included in the mixed ultra wide bandwidth signal and post signal decay of the resultant signal to zero occurs in T S time; and a convertor, coupled to the bandpass filter, converting the resultant signal at the initial peak to a digital output signal wherein T S is a center-to-center clock period for the wavelets in the local ultra wide bandwidth signal.
