  • Parasitic Antenna Arrays for Wireless MIMO Systems – Parasitic Antenna Arrays for Wireless MIMO Systems
    , 2013
    Co-Authors: Antonis Kalis, Athanasios G. Kanatas, Constantinos B. Papadias
    Abstract:

    This book unites two different technologies: parasitic antenna arrays driven via Analogue Circuits that control the electromagnetic waves generated by the antenna array; and MIMO technology for multi-antenna arrays, typically driven by digital techniques in the baseband domain. The combination of these two technologies has revealed a novel functionality that breaks through the conventional MIMO paradigm, allowing MIMO transmission over the air with the use of antenna arrays that may consist of only a single active element, that is surrounded by a number of passive neighboring antennas. The contributions in the book show the capability of such systems to also perform MIMO transmission. This fact holds the potential of revolutionizing the way small-form wireless terminals operate and seems to set the scene for a win-win situation, achieving MIMO transmission with very small and cheap antenna arrays. The book is structured to provide a well-rounded treatment of the various facets of this newly discovered wireless communication capability. All relevant technical angles, ranging from information theoretic to electromagnetic considerations; from Analogue Circuit to digital baseband control for signal generation; and from channel modeling to communication theoretic aspects are taken into account. A good balance between theory, practical considerations and over-the-air experimentation is proposed and reflected in the chapter outline. Finally, a discussion and early evidence related to potential applications as well as the relevance to current and upcoming wireless standards is provided.

  • PRBS testing of Analogue Circuits
    , 1992
    Co-Authors: M.a. Al-qutayri, Peter R Shepherd
    Abstract:

    This paper presents a time-domain approach, for testing Analogue Circuits that can be implemented on a digital tester. The time-domain testing strategy proposed is based on the excitation of the Analogue Circuit-under-test (CUT) with a sequence of pulses, and subsequent measurement of the transient response at the output node/s. Both the transient voltage at the output node/s and the transient current (Idd) of the supply current are measured. The major advantage of the transient response is that it contains all the necessary information about the CUT. This information can then be processed in a number of ways to extract measures of various parameters. In this case the authors process the transient response data to establish whether the Circuit is faulty or not (i.e. Go/No-Go). The test sequence to be applied to an Analogue CUT is a pseudo-random binary sequence (PRBS). The PRBS is chosen because it can be readily generated by a digital tester, such sequences have well defined properties and can be used to extract the impulse response of the CUT if required. The autocorrelation function of a PRBS signal is triangular with a base-width equal to two clock periods, which is a very good approximation of the impulse function. >

  • A prototype supply current monitor for testing Analogue Circuits
    Proceedings. Tenth Annual IEEE International ASIC Conference and Exhibit (Cat. No.97TH8334), 1
    Co-Authors: Mahmoud Al-qutayri, W.j. Tenten, Peter R Shepherd
    Abstract:

    This paper presents the design of a unified supply current monitor for the detection of faults in Analogue Circuits. The emphasis is placed on the design of a monitor with minimum overhead that can be implemented to detect variations in the dynamic supply current. The design of the monitor and the results of using it to detect faults in an Analogue Circuit in a simulation environment are outlined.
