Abstract

Procedimiento y disposición para verificar la calidad de transmisión de un canal de radio en un sistema de radio celular con una estructura-TDMA, en el que al menos la parte móvil (MT) determina periódicamente valores de medición (x{sub,i ) de la intensidad del campo de recepción. Una unidad de evaluación (AW) puede calcular a partir de los valores de medición de la intensidad de campo un valor medio de medición de la intensidad de campo ({x ) así como el cuarto momento (M) y puede determinar la diferencia (D) entre estas dos magnitudes, e igualmente calcular una proporción de errores de cuadros (r{sub,f ) a partir del número de los errores de cuadros.Procedure and arrangement to verify the transmission quality of a radio channel in a cellular radio system with a TDMA-structure, in which at least the mobile part (MT) periodically determines measurement values (x {sub, i) of the intensity of the receiving field. An evaluation unit (AW) can calculate from the field strength measurement values an average field strength measurement value ({x) as well as the fourth moment (M) and can determine the difference (D ) between these two magnitudes, and also calculate a proportion of frame errors (r {sub, f) from the number of frame errors.
