Abstract: A system and method for symbol rate estimation using vector velocity that does not require any prior knowledge of the signal's structure and is accurate in the presence of frequency offset and noise. An input signal is converted to a symbol constellation path signal, and a velocity signal representing a velocity of the symbol constellation path signal is generated. A first frequency spectrum of the velocity signal is generated by performing a Fast Fourier transform on the velocity signal, and a maximum peak value of the first frequency spectrum, a first bin below the maximum peak value, and a second bin above the maximum peak value are identified.

Abstract: A method and apparatus for correcting a phase of a phase-modulated signal for blind demodulation. The method and apparatus generally include the creation of a plurality of angle bins, wherein each constellation point of the phase-modulated signal is assigned to an angle bin, depending on its phase angle. A histogram is formed of the angle bins and cross correlated with a template signal model histogram. The maximum value of the cross correlation determines a correction angle by which the phase angle of all the phase-modulated constellation points is multiplied.

Abstract: A method and system for clinical order entry and decision support are provided. The system and method allow physicians to input orders directly in clinical shorthand. The system presents high-probability choices for order action, determination of clinical context and possible problem solutions. The choices reflect current medical research, patient-specific information and standard practices of other physicians and/or administrators. Selections or edits to the presented choices can be entered quickly and easily, thereby allowing automated generation of complete orders needed to carry out the decisions made. In this way, medical decisions can be made and executed in a fast, efficient and standardized manner.
