    Real-time systolic-array-based implementations of VLSI two-dimensional (2D) infinite-impulse-response (IIR) frequency-planar beam plane-wave filters have potentially wide applications in the filtering of spatio-temporal RF broadband plane waves based on their directions of arrival (DOAs). Distributed-parallel-processor (DPP) implementations of the systolic arrays allow synchronous sampling of the ... View full abstract»

    By pre-equalizing the interlayer interference at the transmitter, the Tomlinson-Harashima precoding (THP) algorithm provides a solution for the downlink of multi-user multiple-input multiple-output (MIMO) systems, in which, because of the absence of cooperation among mobiles, receiver-based layer-separation algorithms cannot be implemented. In this paper, a new THP algorithm using the minimum mean... View full abstract»

    In this paper a useful pseudo-exponential and pseudo-logarithmic circuit is proposed that offers improved performance compared to a current-conveyorbased design. The circuit employs two operational amplifiers and several resistors and mimics the exponential and logarithmic functions over predefined ranges. Control of the pseudo-functions is achieved by a single resistance, which may be digitally s... View full abstract»

    In this paper, the design of a hardware and software system for graphical representation of tactile sensing data is described in detail. The signal processing is developed using LabView 7 software. The signals from the sensors are processed, and then various tactile properties of the grasped material are extracted. The tactile information includes softness, stress distribution, and lumps. This inf... View full abstract»

    Investigations have been carried out with the goal of assessing the trabecular bone thickness of biological samples using images obtained by micro-computed tomography and magnetic resonance imaging. There is no conventional definition of trabecular bone thickness, and many methods may be involved in determining it. However, the results of the available algorithms or software packages differ consid... View full abstract»

    The test access mechanism (TAM) is an important element of test architectures for embedded cores and is responsible for on-chip test pattern transport from the source to the core under test to the sink. Efficient TAM design is of critical importance in system-on-chip integration since it directly impacts testing time and hardware cost. In this paper, an efficient genetic algorithm for designing te... View full abstract»
