An UWB receiver based on a comb filter with shortened delay

We propose a new concept for a comb filter based UWB receiver, where the delay of the analog delay element is shortened. The comb filter receiver can cope with the problems of low SNR, high interference levels, strong narrowband interference and multipath propagation in an excellent way. The main challenge for realization with real hardware is the analog delay element. With our new concept proposal, the delay can be shorter while the performance is maintained. Bit error rates for different scenarios with noise, interference and multipath propagation are discussed.
