A Novel Method To Generate UWB Shaping Pulses Based on Chip pulse

Based on the compression characteristics of chirp pulse, we presented a new method to generate UWB shaping pulses. By using this new method, it does not need to reduce the transmitted power in the whole UWB band to suppress the co-channel interference between UWB and WLAN communication systems. So it can resolve the coexistence problem about UWB and WLAN system. The simulation results show that the power spectral density distribution (PSD) of the pulse generated here can comply with FCC emission mask regulations on UWB, and this pulse has very high spectrum utilization ratio. From the results, we also find that, by using this method, the BER (bit error rate) of the system will be much lower than that of a general UWB system. The co-channel interference problem between UWB and WLAN system can be solved effectively
