Abstract

Patente de Invenção: <B>"REPETIDOR LADO A LADO E CANCELAMENTO ADAPTATIVO PARA O REPETIDOR"<D>. Um sistema repetidor possui pelo menos um elemento de antena doador para se comunicar com uma estação base e pelo menos um elemento de antena de enlace para se comunicar com uma estação remota. Um caminho de enlace ascendente de freq³ência de rádio e um caminho de enlace descendente de freq³ência de rádio são acoplados entre a antena doadora e a antena nula. Um circuito de cancelamento adaptativo em cada um dos caminhos de enlace ascendente de freq³ência de rádio e caminho de enlace descendente de freq³ência de rádio gera um sinal de cancelamento, que quando adicionado com um sinal de freq³ência de rádio em qualquer um dos caminhos de enlace ascendente de freq³ência de rádio e de enlace descendente de freq³ência de rádio, substancialmente cancela qualquer sinal de retroalimentação presente no sinal de freq³ência de rádio.
