Abstract

Una unidad de subscriptor para comunicación inalámbrica, con una estación de base en un sistema de comunicación de subscriptor inalámbrico que incluye una pastilla (FIR) (respuesta de impulso finito), una pastilla DIF (frecuencia intermedia digital), una pastilla (chip) de procesador sencillo y un radio. La pastilla del procesador transcodifica una señal de entrada de voz digital para proporcionar símbolos de entrada digital; demodula una señal de salida recibida de la estación de base para proporcionar símbolos de salida digital; y sintetiza un señal de salida de voz digital a partir de los símbolos de salida.
