    Multicarrier transmission has recently become popular, particularly in the area of wireless broadband access technology. This tutorial overview paper formulates multicarrier transmission from a signal processing point of view and provides an in-depth analytical understanding of its constituent fundamental concepts. Multicarrier transmission and reception principles are first derived for the single... View full abstract»

    The problem of recovering signals from partial fractional Fourier transform information arises in wave propagation problems where the measured information is partial, spread over several observation planes, or not of sufficient spatial resolution or accuracy. This problem can be solved with the method of projections onto convex sets, with the convergence of the iterative algorithm being assured. S... View full abstract»

    An efficient direction-of-arrival (DOA) estimation method for narrowband coherent signals with known waveforms impinging on a uniform linear array is presented. Unlike the maximum likelihood (ML)-based methods such as the WCDEML and parallel decomposition (PADEC) methods, the proposed algorithm is a linear operation-based method. It estimates the DOAs by exploiting the shift invariance property of... View full abstract»

    The paper focuses on the Kalman filtering problem for linear continuous-time systems with multiple delayed measurements. An explicit and simpler solution to the Kalman filtering problem is presented for such systems. The approach applied is the reorganised innovation analysis. The obtained Kalman filter is given in terms of Riccati differential equations. A numerical example is given to demonstrat... View full abstract»
