Journal ArticleDOI
MIMO Radar with Widely Separated Antennas
TL;DR: It is shown that with noncoherent processing, a target's RCS spatial variations can be exploited to obtain a diversity gain for target detection and for estimation of various parameters, such as angle of arrival and Doppler.
Proceedings ArticleDOI
MIMO radar: an idea whose time has come
E. Fishler,Alexander M. Haimovich,Rick S. Blum,Dmitry Chizhik,Leonard J. Cimini,Reinaldo A. Valenzuela +5 more
TL;DR: It is shown that MIMO radar leads to significant performance improvement in DF accuracy, and is carried out in terms of the Cramer-Rao bound of the mean-square error in estimating the target direction.
Journal ArticleDOI
Spatial Diversity in Radars—Models and Detection Performance
E. Fishler,Alexander M. Haimovich,Rick S. Blum,Leonard J. Cimini,Dmitry Chizhik,Reinaldo A. Valenzuela +5 more
TL;DR: The optimal detector in the Neyman–Pearson sense is developed and analyzed for the statistical MIMO radar and it is shown that the optimal detector consists of noncoherent processing of the receiver sensors' outputs and that for cases of practical interest, detection performance is superior to that obtained through coherent processing.
Journal ArticleDOI
Effects of clipping and filtering on the performance of OFDM
Xiaodong Li,Leonard J. Cimini +1 more
TL;DR: This work investigates, through extensive computer simulations, the effects of clipping and filtering on the performance of OFDM, including the power spectral density, the crest factor, and the bit-error rate.
Journal ArticleDOI
Robust channel estimation for OFDM systems with rapid dispersive fading channels
TL;DR: A minimum mean-square-error (MMSE) channel estimator is derived, which makes full use of the time- and frequency-domain correlations of the frequency response of time-varying dispersive fading channels and can significantly improve the performance of OFDM systems in a rapid dispersion fading channel.
