Abstract

"MéTODO E APARELHO PARA PRé-COMPENSAR SUPERPOSIçãO DE PULSOS EM UM SINAL DIGITALMENTE MODULADO". Um método de pré-compensar a superposição de pulsos em um sinal digitalmente modulado compreende as etapas de receber uma seq³ência de pulsos, (62) modular a primeira seq³ência de pulsos para produzir uma primeira seq³ência de pulsos demodulados, (68) demodular a primeira seq³ência de pulsos modulados para produzir uma primeira seq³ência de pulsos demodulados, (70) combinar a primeira seq³ência de pulsos demodulados com a primeira seq³ência de pulsos para produzir uma primeira seq³ência de pulsos de erro, (74) modular a primeira seq³ência de pulsos de erro para produzir uma primeira seq³ência de pulsos de erro modulados; e (78) combinar a primeira seq³ência de pulsos de erro modulados com a primeira seq³ência de pulsos modulados para produzir uma primeira seq³ência de pulsos compensados.
