Abstract	Multiband orthogonal frequency division multiplexing (MB-OFDM) and direct sequence ultra wideband (DS-UWB) systems' performances are studied in interfered AWGN channel. Co-existing systems, i.e., interference, are assumed to be based on the forth-coming 4G. The other source is 100 MHz interference located at IEEE802.11a band. The published studies related to the comparison between MB-OFDM and DS-UWB in interfering environments seems to be unsubstantial in the literature. Therefore, it is crucial to fill this gap. We focus more on MB-OFDM systems, whereas the DS-UWB is applied as a reference. The studied victim systems share the same frequency band and have similar data rates. Simulation results indicate that MB-OFDM system can slightly tolerate interference to achieve reasonable bit error rate level. DS-UWB achieves similar bit error rate level with higher interference-to-signal power ratio than MB-OFDM is able to do. The center frequency of interference has only minor effect on systems' performances. Increasing the bandwidth of the interference reduces the performance in the case of MB-OFDM, whereas DS-UWB seems to be quite resilient to it
