A novel tunable UWB pulse design for narrowband interference suppression implemented in BiCMOS technology
The unique properties of modified Hermite pulses is utilized to develop a novel pulse technique for Ultra Wideband (UWB) communications. The proposed method increases the bandwidth of the pulse up to 10 GHz and overcomes the coexistence problem of UWB and vulnerable narrowband systems through suppressing narrowband interference. Consequently it improves the range of UWB communications by increasing the power, without disturbing the narrowband systems. The pulse technique is implemented in high frequency pulse generation circuits and could be fully integrated in BiCMOS process. The nulls of the frequency response are tuned to be located in a definite narrowband system with the number of the nulls being adjustable too. The prototype has been designed and simulated in 0.18 µm BiCMOS technology. The simulation results are in close agreement with mathematical derivations.
