| Abstract: | Ultra-wideband(UWB) has wide applications in wireless communications,radar detection/imaging,and wireless sensor networks.Due to the broadband width of short UWB pulses,high-speed sampling has become an important technical bottleneck,which significantly limits the rapid development of ultra-wideband systems.Compressive sensing(or Compressed Sensing,CS) is a novel sampling and reconstruction theory that can utilize quite lower rate for accurately sampling,quantization,coding and reconstruction of the compres... |
