Patent ID: 7929913

Claim:
An apparatus comprising: a front end utilizing an adaptive filter to suppress, at least in part, interference in a received Ultra-Wide Band (UWB) signal and produce at least one symbol signal, the front end comprising: a number of branches, each including: at least one digital adaptive filter to generate the symbol signal, at least one analog-to-digital converter coupled to provide digital signals to the at least one digital adaptive filter, at least one delay component to delay a feedback signal, at least two frequency down converter units to facilitate the division of the received Ultra-Wide Band (UWB) signal into two signals each having half the bandwidth of the received UWB signal at least one multiplier to multiply the input signal with the feedback signal, and at least one integrator to facilitate reduction in sampling rate of the at least one analog-to-digital converter produce a symbol signal utilizing, at least in part, the output of the multiplier, wherein energy of the symbol signal that falls within the integration interval and results in a reduction of the required sampling rate; and a phase shift key (PSK) symbol detector to extract information from the symbol signal.
