Abstract

Un receptor de radio-frecuencia (RF) de banda base digital (DBB) incluye un módulo de compensación de filtro de paso alto digital (HPFC) utilizado para suprimir distorsión en variación de retardo de grupo producida por el uso de filtros de paso alto (HPFs) análogos de bajo costo en el receptor. El módulo HPFC digital reduce una frecuencia de corte, establecida por los HPFs para las respuestas de dominio de frecuencia de componente de señal real e imaginaria proveyendo una primera señal de compensación que tiene un primer valor predeterminado (K1). El módulo HPFC digital ajusta la ganancia de la respuesta de paso alto de los dominios de frecuencia de componente de señal real e imaginaria proveyendo una segunda señal de compensación que tiene un segundo valor predeterminado (K2).
