Abstract: A nonlinear conversion system using precision mapping and the method thereof are described. The system includes a source value converter, a mapping table unit, a recovering parameter computing unit, and an output computing unit. The method includes the steps of: receiving an input value; converting the input value into a source value; mapping the source value to a destination value in a limited domain for restricting the calculation within a destination domain; establishing a mapping table by directly selecting a precision according to the destination domain and inverse-mapping back to a source domain; and outputting the destination value according to the mapping table, combining the destination value with a recovering parameter for recovering an output value produced by the nonlinear conversion of the input value.

Abstract: A method of path detection in a multi-path communications system that includes selecting an object for configuring a search window, setting at least one sub-window, wherein the sub-window is smaller in size than the search window, providing a first counter for the object, setting a threshold, selecting a decision period for a duration of the object, and detecting a path in a selected region with the at least one sub-window in a plurality of modes corresponding to the threshold.

Abstract: A method of path selection in a multi-path channel communications system that includes providing path information including at least path parameters and path statuses, setting a plurality of thresholds for the path parameters, comparing the path parameters to the thresholds corresponding to the path parameters, assigning a weighting to the path parameters depending upon comparison with the thresholds, updating the path statuses according to the assigned weighting to the parameters and selecting at least one candidate path according to the updated path statuses.
