Abstract

Un receptor de radio incluye una primera trayectoria de señal que incluye un primer sintonizador configurado para recibir una primera señal a partir de una primera antena, y un primer desmodulador configurado para desmodular símbolos a partir de una salida del primer sintonizador para producir primeras métricas de ramificación derivadas de los símbolos desmodulados; una segunda trayectoria de señal que incluye un segundo sintonizador para recibir una segunda señal a partir de una segunda antena y un segundo desmodulador configurado para desmodular símbolos de una salida del segundo sintonizador para producir segundas métricas de ramificación derivadas de los símbolos desmodulados; un combinador para combinar en proporción máxima las primeras métricas de ramificación y las segundas métricas de ramificación; y circuitería de procesamiento para procesar las primeras y segundas métricas de ramificación para producir una señal de salida.
