    This letter proposes a receiver algorithm for orthogonal frequency division multiplexing (OFDM) with receiver diversity that uses a new multiuser generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by successive interference cancellation with least-square projection for multiuser detection. Simulation results show that the proposed approach achieves ... View full abstract»

    A comb spectrum evaluation problem arises in the channel estimation of pilot symbol-assisted modulation (PSAM) systems and also in the (de)modulation of multichannel communication system based on orthogonal frequency division multiplexing (OFDM). In this letter, we decompose an M-component comb spectrum evaluation with transform length N into 1) a fast Fourier transform evaluation of transform len... View full abstract»

    The discretization of a fractional-order differentiator snu , where nu is a real number 0<nu<1, is an important issue in digital signal processing. This letter gives the analytical expression of the convergents of a continued fraction expansion of the binomial (1+s)nu to get a rapidly convergent, stable, minimum-phase approximation of digital differentiators View full abstract»

    In this letter, we show that a computable tree-like interconnection of parallel/series wave digital (WD) adaptors with memory (i.e., characterized by reflection filters instead of reflection coefficients) is equivalent to a like interconnection of standard (memoryless) adaptors whose peripheral ports are connected to mutators (two-port adaptors with memory). In proving all this, we provide a metho... View full abstract»

  • On Interpolation and Resampling of Discrete Data

    Publication Year: 2006, Page(s):733 - 736
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (135 KB) | HTML iconHTML

    This letter introduces a new representation of discrete signals based on the mathematical notions of functionals and continuous dual spaces. A new and more general sampling theorem is also suggested. Next, the problems of interpolating and resampling discrete signals are addressed; and a general solution using functional interpolation-which is applicable to many different settings-is proposed.

  • Accurate Video Alignment Using Phase Correlation

    In this letter, we present an accurate technique for temporally aligning two video sequences of the same scene captured by nonsynchronized cameras. An iterative procedure is proposed to successively align the sequences in space and time; and the existing two-dimensional phase-correlation method is generalized into three dimensions to achieve subframe accuracy. The ground-truth of subframe temporal... View full abstract»

  • Binary Image Authentication With Tampering Localization by Embedding Cryptographic Signature and Block Identifier

    Cited by:  Papers (16)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (399 KB) | HTML iconHTML

    This letter proposes a novel two-layer blind binary image authentication scheme, in which the first layer is targeted at the overall authentication and the second layer is targeted at identifying the tampering locations. The "flippability" of a pixel is determined by the "connectivity-preserving" transition criterion. The image is partitioned into multiple macro-blocks that are subsequently classi...

  • Blind Equalization of Cross-QAM Signals

    This letter presents two new blind equalization algorithms that are specifically designed for cross-QAM signals. Proposed algorithms minimize the dispersion of the equalizer output with respect to single or multiple cross-shaped zero error contour(s). Simulations and analysis demonstrate the good performance of the proposed algorithms View full abstract»

  • Postprocessing With Wiener Filtering Technique for Reducing Residual Crosstalk in Blind Source Separation

    Publication Year: 2006, Page(s):749 - 751
    Cited by:  Papers (3)

    In this letter, a postprocessing method using the Wiener filtering technique is proposed to reduce the residual crosstalk in frequency-domain independent component analysis (FDICA). By the proposed method, the target signal components remain with little attenuation while the interference components are suppressed. The experimental results show that the proposed method reduces the residual crosstal... View full abstract»

  • Moment Estimation and Dithered Quantization

    This letter examines the influence of low-bit quantization on moment estimators with special emphasis on the 1-bit case. Moment estimators are especially useful if no prior knowledge on the distribution of the observations is available or if an ML approach is analytically intractable or computationally infeasible. In order to arrive at analytical results for this very general case, we focus on a d... View full abstract»

  • Computing Nonlinear \tau -Estimation Based on Dynamic Differential Evolution Strategy

    A novel algorithm named NTDDE to compute the nonlinear tau-estimation based on the dynamic differential evolution strategy is proposed in this letter. We construct a new updating stage for this dynamic differential evolution strategy to generate a population with better performance than before. The experimental evidence has been gathered to show that the proposed algorithm is capable of computing ... View full abstract»

  • Minimization of Utterance Verification Error Rate as a Constrained Optimization Problem

    Publication Year: 2006, Page(s):760 - 763
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (116 KB) | HTML iconHTML

    Since utterance verification (UV) may be treated as a two-class classification problem, it may be improved with discriminative training such as minimum verification error training or minimum verification error rate training. However, since in practice, one usually has to pick a specific false-acceptance or false-rejection rate for one's system, it is more desirable to optimize UV performance at a ... View full abstract»
