Abstract: A visualization system for a wellbore environment includes a graphics processor for creating a computer rendered visual model of a well, and optionally a drill string, based on data sets of depth-varying and/or time-varying parameters of the well. The model is then displayed on a graphics display. A user interface facilitates user navigation along the length of the well to any selected region therein, and further permits user adjustment of orientation of the displayed renderings as well as a temporal selection of the time-varying data to be displayed. Simulated, real, or a combination of simulated and real wellbore data, which may be steady state, transient, or real-time data, may be visually depicted at any selected region. This provides the user with a visual indication of the wellbore environment as the user navigates the visualization spatially and temporally.

Abstract: A method and system are described for performing fast and simple M-QAM detection on received signals, such as a 16-QAM signal, by estimating M-QAM symbol constellation decision boundaries. Amplitude information is collected for in-phase and quadrature phase components of the received signal over a number of symbols. An average of the absolute value of the amplitude information of the in-phase components and of the quadrature phase components is determined over the number of symbols. The determined average absolute values of the in-phase and quadrature phase components provide a reference to produce the decision boundary estimates. Bias compensation may optionally be applied to the decision boundary estimates based on the estimated signal-to-interference ratio (“SIR”) of the received signal to produce bias corrected decision boundary estimates.

Abstract: An amplifier circuit includes a calibration circuit with a controllable circuit element such as a digital resistor. One or more properties of the controllable circuit element (e.g., the resistance in a digital resistor) is varied by a digital calibration word such that the voltage drop across the resistor matches a reference voltage. The calibration word is also used to control the resistance of a transistor that forms a part of a power amplifier to compensate for temperature and process variations. The amplifier may be a switching power amplifier, and the transistor may be a segmented transistor with the width (and hence the channel resistance) controlled by the digital calibration word.

Abstract: Methods and structures for quickly and accurately measuring interference associated with a received signal in a CDMA radiocommunication system are described. Interference measurement is performed by despreading a received signal using a channelization code which is reserved from a finite set of orthogonal channelization codes. The reserved code is not used (or is rarely used) for spreading traffic and, therefore, provides an estimate of the interference associated with a received signal when a receiver correlates the received signal with the reserved code.
