A Novel Channel Estimation Technique for Complexity Reduction of Least Minimum Mean Square Error

Abstract

Performance comparison of several channel estimation techniques in the downlink of LTE systems was performed based upon the algorithm’s complexity which varies according to the density of the channel matrix. In this study has been presented a proposed channel estimation technique whose complexity is invariant with the number of multipath components in fast fading channels. The proposed channel estimator is derived by a review of the mathematical model of the received OFDM signal in the down link of LTE systems its performance is evaluated using the mean squared error as the performance metric of interest. Also a study of the effect of the proposed channel estimation technique on the bit error rate performance of the downlink of LTE systems is also investigated numerically through simulation

A New Method for Multipath Clustering for Over-the-Horizon Radar

“…Some of these applications are diversity communication systems (El-Ansary et al, 2013;Aziz, 2011a), target detection (Aziz, 2010;El-Ayadi et al, 1996), distributed radar surveillance networks (Aziz, 2014c;Aziz, 2008), wireless sensor networks (Aziz et al, 2011;Aziz, 2011b), biomedical applications (El-Badawy et al, 2014;2013) and target tracking (Aziz, 2013;2011c). An association technique is essential processing in multisensor data fusion systems (Hall, 1992).…”
