  • Weather influence on Loran-C

    Creator:
    Graulich, Markus Günter
    Abstract:
    The influence of weather on the long range radio navigation system Loran-C was investigated. The variables analyzed over a period of 255 days were: time differences (TDs), TD signal-to-noise ratios, TD standard deviations (measured at a fixed receiver location in Corvallis, Oregon), time interval numbers (TINOs) (measured at the transmitter...

  • 5th-Order Elliptic LPF Using Passive Charge Compensation Technique (PCC) Design

    Creator:
    Tsai, Cheng H.
    Abstract:
    The passive charge compensation (PCC) technique was introduced for switched capacitor (SC) circuit to increase the slew rate and enhance the linearity performance, as PCC techniques are used on the Delta-Sigma modulator (DSM) in ADC circuitry. The PCC technique of the project was applied to the design of a SC...

  • COLAN V : a high performance local area network for control and communication utilizing a communication co-processor

    Creator:
    Kumar, Ravi C.
    Abstract:
    This paper describes the design and implementation of COLAN V, a High Performance Local Area Network for Communications and Control utilizing a Communications Coprocessor. The main objective of this thesis is to improve upon the performance of previous COLANs in speed, switching techniques and error detection techniques. This was possible...

  • Tone burst deconvolution

    Creator:
    Rathja, Roy C.
    Abstract:
    The suitability of discrete least-squares optimal (Wiener) filters for deconvolution of tone-burst waveforms is studied. It is shown that: (1) such waveforms are not well suited to these filters without preprocessing, (2) the use of exponential weighting results in a significant improvement in filter performance and (3) that "phase-unwrapping" in...

  • A programmable network interface unit for hybrid meshnet local area networks

    Creator:
    Merchant, Shashank C.
    Abstract:
    A Hybrid Meshnet LAN, a new local area network architecture, has been proposed by Dr. Cheoul-Shin Kang and Dr. James Herzog. It provides for distributed control hybrid architecture which is good for effective load sharing under various local area network environments. Hybrid Meshnet has a dual channel structure, a token...

  • LORAN-C receiver position estimation from noisy time-difference data

    Creator:
    Weisshaar, Andreas
    Abstract:
    In order to analyze the accuracy of the navigation system LORAN-C, we have collected time - difference (TD) data from the U.S. west coast chain (9940) at a fixed receiver location (Corvallis, Oregon). The analysis of the TD data shows an unexpected high correlation between the TDs as well as...

  • Analog integrated circuit design using GaAs C-HFETs

    Creator:
    Gupta, Rakhee
    Abstract:
    Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

  • The design of delta-sigma modulators for multi-standard RF receivers

    Creator:
    Liu, Mingliang
    Abstract:
    The transition from second-generation (2G) to third-generation (3G) wireless cellular and cordless telephone systems requires multi-standard adaptability in a single RF receiver equipment. An important answer to this request is the use of Delta-Sigma modulators for IF-to-baseband conversion, which will satisfy the dynamic range requirements for digital signal processing, and...

  • Analysis and design of bandpass delta-sigma A/D converters

    Creator:
    Zhai, Dalun
    Abstract:
    A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...
