Research on orthogonal wavelet synthesized UWB waveform signal

Based on the Haar wavelet synthesized narrow pulse technique, the paper initially puts forward a diversity receiving and transmitting technique of Haar waveform (WD) of UWB signal. The narrow pulses synthesized by each order of Haar wavelet are sent to the receiving system through the transmitting system. The receiver uses coherent detection technique to detect each order of Haar wavelet, which can extract accurately each order of Haar wavelet in the transmitted UWB narrow pulse. The proposed method has important significance for the practical applications due to the easier implementation of Haar wavelet.
