Performance Analysis of Bit Error Rate for Impulse Ultra Wideband in the AWNG

Aiming at Time-Hopping Ultra Wideband(TH-UWB) and Driect-Sequence Ultra Wideband(DS-UWB) in the Additive White Gaussian-Noise(AWGN) jamming,an analysis is processed for the Bit Error Rate(BER) performance.and then the bit error rate between Pulse Position Modulation(PPM) and Pulse Amplitude Modulation(PAM) in the ultra wideband singal is compared.Bying both theoretical analysis and software simulaton,the result explains that the bit error rate performanece of pulse amplitude modulation is superior to the pulse position modulation′s for both the time-hopping ultra wideband and the direct-sequence ultra wideband.On the basis of it,some methods are given for the ultra wideband impulse signal to improve the ability of resisting to the additive white gaussian-noise.
