    The normal-mesh-based image coder of Jansen, Baraniuk, and Lavu (JBL) is studied. First, the JBL coder is introduced, and several of its shortcomings are identified. Then, to address these shortcomings, three modifications to this coder are proposed, namely, the use of a data-dependent base mesh, an integer representation for normal/vertical offsets, and a different scan-conversion scheme based on...

    An automatic segmentation method for medical images that uses a geometric deformable model is presented, and the segmented results are visualized with the help of a modified marching cubes algorithm. The geometric deformable model is based on evolution theory and the level set method. In particular, the level set method utilizes a new derived speed function to improve the segmentation performance.... View full abstract»

    In Web mining applications, an enormous amount of data needs to be processed quickly and efficiently. Thus, hardware support is crucial to enhance the performance of these operations. In this work, chip-level hardware support for similarity measure calculation is introduced and then extended to similarity matrix computation. Both software and hardware versions of various similarity computations ar... View full abstract»

    A high-level VLSI design platform, called CoDeL, which allows hardware description at the algorithm level and thus dramatically reduces design time, is presented. It now directly supports the use of fixed-point operations to ease description of digital signal processing (DSP) algorithms. Also, to dramatically reduce dynamic power dissipation in the resulting architecture, it automatically inserts ... View full abstract»

    This paper considers the use of space division multiple access (SDMA) techniques for the uplink of multi-carrier code division multiple access (MCCDMA) systems, where the transmitted signals face strong nonlinear distortion effects. The signal transmitted by each mobile terminal (MT) is submitted to a nonlinear operation consisting of a clipping device followed by a frequency-domain filtering oper... View full abstract»

  • A novel complementary sequence and PMEPR reduction in OFDM

    This paper introduces a novel sequence called the "beta-complementary sequence" to encode orthogonal frequency-division multiplexing (OFDM) signals, with which one can substantially increase the code rate while maintaining a tight peak-to-mean envelope power ratio (PMEPR) of at most 2. Moreover, encoding schemes based on beta-complementary sequences provide very good tradeoff performance between P... View full abstract»
