  • A fast high-performance array processing technique for angle-of-arrival estimation and detection of the number of incident signals

    A new projection-based algorithm is proposed for estimating the angles of arrival of plane waves incident onto arrays of sensors. The method is based on a single QR decomposition of the signal covariance matrix; hence, it is much faster than eigen-based methods, which require many QR decompositions. It is shown that optimum performance is attained only if the columns of the covarianc... View full abstract»

    Two methods are presented for extending the threshold characteristics of the modified forward-backward linear prediction (MFBLP) algorithm due to Tufts and Kumaresan (1982). This algorithm estimates angles of arrival of plane waves onto linear arrays of sensors. The first technique proposed, referred to as modified-modified FBLP (M2FBLP), offers 4- to 6-dB threshold extensions over MFBL... View full abstract»

  • Co-ordination of thyristor-controlled VAr compensator and auxiliary controller of excitation system for small signal stability enhancement

    Publication Year: 1989 , Page(s): 55 - 62

    Technical advantages of co-ordinating thyristor-controlled static VAr compensators (SVC) and power system stabilizers (PSS) for stability enhancement during small signal dynamics are presented. The technical feasibility of the co-ordinated scheme for simultaneous damping of inertial and torsional oscillatory modes in a series-capacitor-compensated system is demonstrated. The investigations show th... View full abstract»

  • Fast-decoupled transient stability

    Publication Year: 1989 , Page(s): 63 - 66

    Presents an improved method for computing transient stability using a fast-decoupled formulation of the transient energy function. The new formulation offers significant savings in computer time as compared to the existing Newton-Raphson formulation. It therefore represents a suitable technique for online transient stability computations in utility control centres. View full abstract»

  • Minimal multiplexer realization of logic functions

    Publication Year: 1989 , Page(s): 67 - 71

    It is well known that any n-variable logic function can be realized by a multiplexer (selector) with no additional external logic. Thus multiplexers have come to be known as universal logic modules. This approach to logic function realization requires the use of a 2n-input multiplexer with constant data inputs, or a 2n-1-input multiplexer whose data inputs are constant... View full abstract»

  • Quantization noise and eigenvalue statistics in the stochastic gradient polarity adjustment of an adaptive equalizer

    Publication Year: 1989 , Page(s): 72 - 80

    An experimental adaptive decision feedback equalizer (DFE), with jointly adjusted sampling phase, and which employs a decision-directed stochastic gradient polarity (DDSGP) algorithm, is described. Measured performance with respect to odd-order multipath frequency response is found to be significantly worse than the calculated mean square error performance which does not include quantization noise...
