  • Some contributions to asymmetric error control codes

    Creator:
    Elmougy, Samir
    Abstract:
    In some practical systems, most of the errors are of 1 → 0 type and 0 → 1 errors occur very rarely. In this thesis, first, the capacity of the asymmetric channel is derived. The capacity of the binary symmetric channel (BSC) and the Z-channel can be derived from this...

  • Modified VLSI designs for error correction codes

    Creator:
    Chen, Lupin
    Abstract:
    Nowadays, error correction codes have become an integral part in almost all the modern digital communication and storage systems. With the continuously increasing demands for higher speed and lower power communication systems, efficient VLSI implementations of those error correction codes have great importance for practical applications. In this thesis, several...

  • Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

    Creator:
    Guerber, Jon
    Abstract:
    In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...

  • Variable sampling compensation of networked control systems with delays using neural networks

    Creator:
    Lopez-Echevarria, Daniel
    Abstract:
    In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...

  • Efficient VLSI architectures for MIMO and cryptography systems

    Creator:
    Li, Qingwei
    Abstract:
    Multiple-input multiple-output (MIMO) communication systems have recently been considered as one of the most significant technology breakthroughs for modern wireless communications, due to the higher spectral efficiency and improved link reliability. The sphere decoding algorithm (SDA) has been widely used for maximum likelihood (ML) detection in MIMO systems. It is...

  • Position estimation in indoor localization with trilateration

    Creator:
    Su, Zhenqiang
    Abstract:
    Triangulateration uses geometric distance to estimate the location of user by employing techniques like received signal strength (RSS), time-of-arrival (TOA), time-difference-of-arrival (TDOA) and image processing. Radio frequency (RF) signal positioning using TOA or TDOA techniques generally requires timing synchronization of the anchors and/or the anchors and targets. If the desired...

  • Non-data aided parametric based carrier frequency estimators for bursty GMSK communication systems

    Creator:
    Kandukuri, Ajay
    Abstract:
    Estimating the carrier frequency from a modulated waveform is one of the most important functions of a coherent signal receiver. Good performance and low bit error rates are obtained by coherent demodulation. Therefore, exact knowledge of the received signal carrier frequency is critical for communication systems. Also due to the...

  • Channel Estimation in TDD Massive MIMO Systems with Subsampled Data at BS

    Creator:
    Tian, Yichuan
    Abstract:
    Massive MIMO is a promising technique for future 5G communications due to its high spectrum and energy efficiency. To realize its potential performance gain, accurate channel state information at transmitter side (CSIT) is essential. Frequency division duplex (FDD) is widely employed by the most cellular systems today. However, it requires...
