Abstract

A transmitter location searching system produces fast, stable and accurate results in a multipath transmission environment by geometrically partitioning the monitored area into a plurality of cells and finding the optima of a total cost function at the centers of the cells. The original three-dimensional optimization problem is thus reduced to a one-dimensional problem. Based on this calculation, the cell providing the smallest cost is chosen as a new candidate cell which is divided into smaller cells and the minimum costs are calculated for each of these smaller cells. The cell that provides the smallest cost is chosen as the center of another new candidate cell. The process is iterated until a dimension of a new candidate cell is smaller than a predetermined threshold. By reducing the dimensions of each cell by a factor of two at each iteration, the algorithm converges rapidly.
