  • In usual spatial-time processing for diversity reception of UWB pulses, the channel delays are not easy to be implemented accurately. This paper firstly discusses the principle of UWB pulse array beamforming. Then a beamforming scheme is presented based on multi-rate filter bank, which is suitable for UWB pulse signals. The proposed method avoids the hardness of delays control in time domain, and can obtain the uniform frequency invariant array response in such a wideband for UWB signals. The way of realizing the multi-rate filtering is analyzed in detail, and it proves to be of easy design. Moreover, its computational cost is independent of the number of subbands. Additionally, the discontinuity of UWB pulse signals makes it possible to employ a relatively simple interpolation algorithm in time domain. The simulation results verified the feasibility and the effectiveness of this presented method.
