Effects of timing jitter in low-band DS-BPSK UWB system under Nakagami-M fading channels

The effects of timing jitter in direct sequence binary phase shift keying (DS-BPSK) ultra wideband (UWB) systems applying the FCC-constraint pulses are investigated under at Nakagami-m fading channel and additive white Gaussian noise (AWGN). The numerical results show that two FCC-constraint pulses, Low band (LB)-PSP and LB-MMNHP, have almost same sensitivity to the timing jitter even though they have different transceiver complexity. Additionally, the additional power caused by the timing jitter exponentially increases, but the additional power caused by the amplitude fading is not exceeded over 7 dB.
