    Abstract: A method and apparatus for use in a hybrid position location system. The method and apparatus combines measurements from Global Positioning System (GPS) and terrestrial transceiver stations to compute the location of a device. An algebraic solution to hybrid position location system equations is output from the method and apparatus. The method and apparatus determines the position of a device using a non-iterative method, as against the use of a conventional iterative least mean square method. The method of the present invention can be used to solve the location system equations in scenarios where a non-iterative solution is desirable. In certain scenarios, the location system equations may have two possible solutions. An iterative method would converge on one of the solutions, without any indication of the existence of the other ambiguous solution. Moreover, the iterative method may converge on the incorrect of the two ambiguous solutions. Use of the presently disclosed method and apparatus yields both the ambiguous solutions. The disclosed method may be followed up with iterative methods, using the solutions from the algebraic method as initial estimates of the device location for the iterative method. A different process can then select the correct solution. Thus, the algebraic method can be used to detect the existence of ambiguous solutions, and to find both solutions.

    Abstract: A method for providing an estimate of a received signal strength comprising receiving a signal, the received signal comprising a desired signal; measuring an energy of the desired signal to provide a measured energy, the measuring further comprising first integrating the desired signal over a first predetermined interval to provide an averaged energy, and second integrating the averaged energy over a second predetermined interval to provide the measured energy; and estimating a signal strength of the desired signal in accordance with the measured energy, wherein the estimated signal strength is indicative of the received signal strength. A signal strength estimator adapted to perform the method is also described.

    Abstract: A method and apparatus for sequentially synchronized timing and frequency generation in a communication network includes a parent station for maintaining system time and frequency values, a time/frequency transfer unit for receiving and demodulating the system time and frequency values from the parent station and generating corrected system time and frequency values by adjusting a clock and the center frequency of a pilot signal at a child station to remove time and frequency discrepancies, and a child station to which the time/frequency transfer unit directly communicates the corrected system time and frequency values. The child station become a parent station upon communication of the corrected system time and frequency values. The sequence may be repeated for as many stations as are deployed in the network.

    Abstract: Un procedimiento para mejorar la sensibilidad de un receptor (400) de un sistema de localización global (GPS), incluyendo el procedimiento los pasos de: recibir (801) una señal del GPS a partir de un satélite del GPS; recibir (803) información de temporización desde un origen para la sincronización con la hora del GPS, distinto al mismo satélite del GPS; determinar, a partir de la información de temporización, límites de bit de una pluralidad de bits de información en la señal recibida del GPS; correlacionar la señal recibida del GPS con un código predeterminado asociado a un satélite seleccionado entre una pluralidad de satélites del GPS durante cada uno entre una pluralidad de periodos de código; integrar coherentemente los resultados de la correlación determinados durante cada periodo de código, a fin de determinar un resultado total de correlación integrada sobre la pluralidad de periodos de código; y procesar la señal recibida del GPS usando información acerca del satélite seleccionado si el resultado de correlación integrada es mayor que un valor de umbral.

    Abstract: Systems and methods are provided for sending and receiving information over different bandwidths, using a shared baseband processor. The transmission method selects clock sampling frequencies, for example a first clock frequency ( l x F1), or a second clock frequency ( k x F1), where k > l . Digital information is processed using the selected clock sampling frequency and a baseband signal is generated. Regardless of the clock sampling frequency selected, the baseband signal may have the same number of subcarrier frequencies. The baseband signal is converted into a radio frequency (RF) signal having a data rate responsive to a selected clock frequency, and transmitted. More explicitly, a first baseband signal is generated having a first data rate in response to selecting the first clock frequency. A second baseband signal having a second data rate greater than the first data rate, may be generated in response to selecting the second clock frequency.
