Abstract

Al transmitir senales de comunicacion a un receptor a través de un canal de transmision, el transmisor genera una senal compuesta que incluye informaciona partir de la cual el receptor puede determinar una senal de evaluacion de canal y otrainformac ion de control. La senal compuesta se transmite a través delcanal de transmision. Esto da como resultado una mayor capacidad del canal, menores requerimientos de transmision de potencia y menor interferencia en el canalde transmision.
