Abstract
Un metodo para seleccionar una solucion de determinacion de ubicacion de entre un conjunto de posibles soluciones de determinacion de ubicacion generadas a partir de senales de amplitud filtradas, no filtradas, y escasamente filtradas; la solucion se calcula utilizando un primer algoritmo y senales de amplitud filtradas para obtener una solucion de determinacion de ubicacion filtrada; soluciones de determinacion de ubicacion adicionales se calculan utilizando un segundo algoritmo con senales de amplitud no filtradas para obtener una o mas soluciones de determinacion de ubicacion no filtradas; ademas, soluciones de determinacion de ubicacion adicionales se pueden calcular utilizando un tercer algoritmo con senales de amplitud escasamente filtradas para obtener una o mas soluciones de determinacion de ubicacion escasamente filtradas; se elige una solucion de determinacion de ubicacion final de entre el conjunto de soluciones de determinacion de ubicacion filtradas, soluciones de determinacion de ubicacion no filtradas, y soluciones de determinacion de ubicacion escasamente filtradas a traves de una metrica de optimizacion, M.
