  • Hybrid method for full identification of buried objects and surrounding media 

    Abrishamian, M. S.؛ Haghparast, M.؛ Mirtaheri, S. A. (Shahed University, 2013-09-01)
    This study describes a hybrid technique for identification of buried objects. The object s shape and electromagnetic profile are reconstructed from evaluations of electrical permittivity and conductivity. The method suggests ...

  • High Frequency Analysis of Single Overhead Line Terminated to Grounded Arrester 

    Taghavi, S.M. (Shahed University, 2013-09-01)
    In this paper, intelligent models based on fuzzy inference are proposed to analyze single overhead line terminated to arrester. This paper consists of two parts. The first one is modeling overhead line and the second one ...

  • Fractional Fourier Transform Based OFDMA for Doubly Dispersive Channels 

    Sabbaghian, M.؛ Mokhtari, Z. (Shahed University, 2013-09-01)
    The performance of Orthogonal Frequency Division Multiple Access (OFDMA) system degrades significantly in doubly dispersive channels. This is due to the fact that exponential sub-carriers do not match the singular functions ...

  • Reduction of CRB in Arbitrary Pre-designed Arrays Using Alter an Element Position 

    bakhshi, hamidreza (Shahed University, 2013-09-01)
    Simultaneous estimation of range and angle of close emitters usually requires a multidimensional search. This paper offers an algorithm to improve the position of an element of any array designed on the basis of some certain ...

  • A Non-MDS Erasure Code Scheme for Storage Applications 

    Akhlaghi, Sorosh؛ Kiani, A. (Shahed University, 2013-09-01)
    This paper investigates the use of redundancy and self repairing against node failures indistributed storage systems using a novel non-MDS erasure code. In replication method, accessto one replication node is adequate to ...

  • Bounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel 

    Osmani-Bojd, M.؛ Sahebalam, A.؛ Ahadi, M. (Shahed University, 2013-09-01)
    In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel ...
