    Currently, detect and avoid (DAA) techniques of UWB have been paid large attention because it has been regulated in Japan and Europe. In this paper, a novel signal detection scheme for coexistence of UWB and the 4th generation mobile communication systems is proposed. The proposed scheme makes use of multipath through fractional sampling. The probabilities of false detection and false alarm with fractional sampling in a MB-OFDM receiver are investigated. The numerical results show that the proposed scheme with fractional sampling improves the probability of false detection by about 10 times as compared to conventional schemes. The numerical results also prove that the DFT size can be reduced without increasing the probability of false detection.
