Abstract

MéTODO DE EQUALIZAçãO ADAPTATIVO AUTOMáTICO E SISTEMA PARA LINK DE TRANSMISSãO SERIAL DE ALTA VELOCIDADE. Um sistema de comunicação de dados (900) inclui uma unidade transmissora (100) e uma unidade receptora (200). A unidade transmissora (100) tem uma característica de transmissão que é ajustável de acordo com a informação de equalização. A unidade transmissora (100) é operável para transmitir um sinal pré-determinado e a unidade receptora (200) é operável para receber o sinal pré-determinado. A unidade receptora (200) é ainda operável para gerar a informação de equalização, examinando a abertura de olho do sinal recebido, e transmite a informação de equalização para a unidade transmissora (100).
