Abstract

Un método en relación con sistemas de comunicación de radio móviles digitales para formar, en un receptor, una medida SQ de calidad del vector de la señal recibida en una ráfaga de señales que comprende formar un primer cálculo Es de la energía de la señal útil del vector de la señal, formar un segundo cálculo En de la energía de los componentes restantes de la señal del vector de señal y formar la medida SQ de la calidad del vector de la señal de conformidad con la fórmula SQK1Es/(K2+En) en donde K1 y K2 son constantes predeterminadas.
