摘要： A method for determining which of a plurality of data connectivity pipes will be used to transmit data for one or more applications operating on a vehicle. The method identifies which of the applications are active at a particular point in time and identifies a number of available configurations based on the number of applications that are active and the number of the data pipes that are available to transmit the data for the application. The method identifies a plurality of performance metrics for each configuration and determines an optimal performance value for each performance metric from all of the configurations. The method then determines an overall utility function for each configuration that is based on its performance metrics and the optimal performance value and selects a data pipe for each application that is active based on a maximum overall utility function from each application's available overall utility functions.

摘要： A method for estimating signal quality of a spread spectrum signal is provided. The method includes squaring a plurality of in-phase correlation results and a plurality of quadrature correlation results, summing each squared in-phase correlation result and the corresponding correlation result to obtain a plurality of sum-of-square values, detecting a peak value among the plurality of sum-of-square results, calculating an average of non-peak values among the plurality of sum-of-square results. The peak value is regarded as a signal power value, while the averaged non-peak values are regarded as an average noise power value. A signal-to-noise ratio is then calculated based on the signal power value and the average noise power value. A method for determining the parameters for the tracking loop is also provided. The method includes estimating the signal-to-noise ratio of the spread spectrum signal, and determining the tracking loop parameters based on the signal-to-noise ratio.
