    Due to the increasing interest in mobile/wireless communication, there has been a continuous research in antenna diversity to combat fading. And the model of correlated and unbalanced diversity branches reflects the real-world scenario. The diagonalizer is introduced here before the diversity branches are combined, which can transform the correlated and balanced branches to the uncorrelated and un... View full abstract»

    Single tone, low baud rate modems are used in communications over shortwave radio channels. A modified Goertzel algorithm that rapidly acquires signal parameters under adverse conditions is used. By applying frame excision, a single tone modem that is more tolerant to intersymbol interference and frame synchronization errors may be designed. View full abstract»

  • A Minimum Phase Space Distance method for the demodulation of M-ary chaotic parameter modulation

    Publication Year: 2004, Page(s):15 - 19
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1504 KB) | HTML iconHTML

    An M-ary modulation scheme for chaotic spread spectrum communication is proposed by employing a generalized tent map to modulate binary messages. Binary bit streams are represented by noise-like and broadband chaotic sequences generated from a generalized tent map with different parameter sets. Due to the broad parameter range that can drive this kind of generalized tent map to chaotic behavior, m... View full abstract»

    In this paper, we focus on the security issue of a chaotic digital communication scheme called chaotic-pulse- position modulation. We design a third party intrusion scheme to test to see if CPPM is as secure as is claimed. Experiments are conducted with various chaotic maps, where CPPM is used to modulate the message at the transmitter and a Kalman filter fed with a polynomial approximation is use...

    This paper describes a method of calculating the transforms, currently obtained via Fourier and reverse Fourier transforms. The method allows calculating efficiently the transforms of a signal having an arbitrary dimension of the digital representation by reducing the transform to a vector-to-circulant matrix multiplying. There is a connection between harmonic equations in rectangular and polar co... View full abstract»

    Visual inspection is the commonly used method for bridge deck inspection. However, this method depends on the intuition of the inspector and his experience. The deteriorated condition of the nation's infrastructure requires better techniques for evaluation. Nondestructive evaluation can verify the integrity of a structure or any of its components without compromising its ability to perform in serv... View full abstract»

  • Evolving stability in bipedal robotic systems

    Publication Year: 2004, Page(s):82 - 91
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2882 KB) | HTML iconHTML

    In order for a bipedal robotic system to interact with its environment it must be able to have stability. And because an environment can be composed of different types of terrain and surfaces, adaptation must be part of system behavior. Many current bipedal systems (e.g. Honda's P3 and Asimo or Sony's) utilize high torque custom designed servos and/or control systems to handle specific terrain (fl... View full abstract»
