Abstract

Un método de prueba para determinar sensibilidad del receptor de radiofrecuencia (RF) conducida utilizando una fuente de RF acoplada a un receptor de RF mediante un cable de RF puede incluir una proporción de bits erróneos (BER) contra la función de nivel de potencia de canal de tráfico (TCH) para un canal inicial, determinar un nivel de potencia de TCH estimado para un canal subsecuente basándose en la función y la BER deseada, y medir una BER de canal subsecuente basándose en el nivel de potencia de TCH estimado. La BER medida puede comprarse con la BER deseada, y una diferencia entre las mismas se utiliza junto con la función para determinar un siguiente nivel de potencia de TCH estimado. Medir y comparar puede repetirse si la diferencia puede ser mayor que un umbral para determinar por consiguiente un nivel de potencia de TCH en el canal subsecuente que corresponde a la ver deseada.
