摘要：
In this paper, we compare the effects of multiband orthogonal frequency-division multiplexing (MB-OFDM) and direct-sequence ultra-wideband (DS-UWB) interference on a narrowband (NB) signal. For this purpose, we first derive an analytical expression for the moment generating function (MGF) of DS-UWB interference. Based on this result we obtain an expression for the bit error rate (BER) of a binary phase-shift keying (BPSK) NB signal impaired by DS-UWB and additive white Gaussian noise which lends itself to efficient numerical evaluation. We show that for NB signal bandwidths much smaller than the DS-UWB bandwidth the NB system performance strongly depends on the carrier frequency offset between the NB signal and the DS-UWB signal and we derive corresponding BER approximations. Finally, we show that whether MB-OFDM or DS-UWB interference leads to less performance
