By using the sparsity of frequency hopping(FH) signals,an underdetermined blind source separation(UBSS) algorithm is presented. Firstly, the short time Fourier
A polynomial-rooting based fourth-order cumulant al-gorithm is presented for direction-of-arrival (DOA) estimation of second-order ful y noncircular source sign
Over the past few decades, the world has witnessed a rapid growth in mobile and wireless networks(MWNs) which significantly change human life. However, prolifer
In a system based on the phase lock loop(PLL), a trade-off must be made between the tracking precision and the dynamic performance if constant parameters are ad
In order to improve the survivability of the aircraft,conceptual design and radar cross section(RCS) performance research are done. The CATIA software is used t
