— The single link performance of UWB systems in the AWGN UWB channel is investigated. Based on Cognitive Radio(CR) spectrum allocation and the restriction of Federal Communications Commission (FCC) emission mask, the second derivative Gaussian pulse with the diverse shaping factors and the diverse spectral moving factors act as basis functions. The iterative combination pulse method is put to use to design pulses. The time domain waveform of iterative combination pulse based on FCC signed as UWB system 1. The time domain waveform based on cognitive radio signed as UWB system 2 and UWB system 3. The single link bit error probability (BER) of three different pulse (UWB system 1, UWB system 2 and UWB system 3) for UWB system in Additive White Gaussian Noise (AWGN) channel are simulated and compared. The better performance and stability are validated based on cognitive radio UWB pulse for UWB system.
