    Abstract

    A low-complexity cycIostationarity feature detection scheme is proposed in this paper. Such method is suitable for the detection of a localized Single-carrier Frequency Division Multiple Access (SC-FDMA) signal. SC-FDMA scheme is the candidate for the uplink of Long Term Evolution-Advanced (LTE-Advanced) system. The detection of the uplink signal is critical to the coexistence between UWB systems and LTEAdvanced systems. The proposed scheme requires low computational complexity at the cost of slight reduction in detection performance. Simulation results and computational complexity analysis indicate that the proposed scheme makes a tradeoff between detection performance and computational complexity. In a worse transmission environment, the low-complexity cycIostationarity feature detection can be utilized as a substitute for the energy detection since the later approach is sensitive to noise uncertainty and can not work well in such circumstance.
