Abstract

SE PRESENTA UN METODO Y UN APARATO PARA CONTROLAR UN SISTEMA ANTICIPADO, COMPENSADO DE AMPLIFICADOR DE ENERGIA QUE UTILIZA UNA TECNICA DE ESPECTRO ESPARCIDO PARA CUBRIR UNA SEÑAL O SEÑALES DE CONTROL E INYECTA UNA SEÑAL COMPUESTA EN UN PUNTO ADECUADO DENTRO DEL SISTEMA AMPLIFICADOR ANTICIPADO PARA REDUCIR LA DISTORSION. LA CANTIDAD DE ESPARCIMIENTO DE LA BANDA ANCHA SE GOBIERNA MEDIANTE LA CANTIDAD DE GANANCIA DE PROCESAMIENTO QUE SE NECESITA EN EL PROCESO DE REMAPEADO Y DEL TIEMPO QUE SE NECESITA PARA LA RESPUESTA DEL SISTEMA. LAS SEÑALES DE CONTROL DESPUES DEL REMAPEADO DEL ESPECTRO DISTRIBUIDO EN LA SALIDA DEL SISTEMA SE CORRELACIONA EN UN CORRELACIONADOR DE FILTRO DE EQUILIBRADO Y EL RESULTADO SE UTILIZA PARA CONTROLAR, EN LAS COORDENADAS TANTO POLARES COMO CARTESIANAS, LA INYECCION, EN FASE OPUESTA, DE LA DISTORSION EXTRAIDA DENTRO DE LA SALIDA DEL AMPLIFICADOR.
