Abstract	To digitize the ultra-wideband (UWB) signal at its Nyquist rate, a frequency channelized receiver for UWB radio based on hybrid filter banks (HFB) is presented. Among the challenges of such receivers are the uncertainties of the analog analysis filters and the slow convergence speed. To overcome these problems, the channelized receiver operates slightly above the critical sampling rate. The proposed receiver, which is designed for use in transmitted reference (TR) systems, combines the synthesis filters and the matched-filter so that only the estimation of the combined response of the analysis filter and the propagation channel is necessary. The resulting convergence speed is comparable to an ideal full band receiver. In addition, all of the receiver functions are performed at the reduced subband sampling rate, relaxing the requirements on the digital circuitry.
