    Abstract: A method, apparatus and system for downlink pilot transmission solve the problem of power differences among OFDM symbols caused by Walsh Codes. The transmission method is that dedicated pilots are transmitted in the manner of code division multiplexing (CDM) or hybrid of CDM and frequency division multiplexing (FDM), wherein the dedicated pilots are configured with orthogonal sequence sets according to a preset frequency-domain granularity and rules on the resources for transmitting the dedicated pilots, and the same orthogonal sequence set is employed for the dedicated pilots in each frequency-domain granularity.

    Abstract: A phase locked loop and an associated alignment method are provided. A disclosed phase locked loop receives a reference signal to provide a feedback signal. The phase locked loop is first opened. When the phase locked loop is open, a frequency range of an oscillating signal from a voltage-controlled oscillator is substantially selected. The feedback signal is provided according to the oscillation signal. After the frequency range is selected, the phase locked loop is kept open and the phases of the reference signal and the feedback signal are substantially aligned. The phase locked loop is then closed after the reference signal and the feedback signal are aligned.

    Abstract: A method of developing a petroleum reservoir from a reservoir model and optimized history matching is disclosed having application for petroleum reservoir characterization. A global objective function measuring the differences between the measured historical data and the simulated historical data is defined according to M parameters. The global objective function is then decomposed into a sum of k local objective functions. Each local objective function measures the differences on a geographic region from mk parameters, selected from among the M parameters, and having a significant impact on the historical data of the region. The region is determined by minimizing this number mk of parameters. The model is then modified by minimizing the global objective function by a gradient method wherein the derivatives of the local objective functions are estimated by means of a parameter perturbation technique. For each local objective function, the perturbation matrix has a rank equal to the number of parameters mk of the local objective function. Finally, the calibrated model is used to develop the reservoir.
