Abstract

resumo a presente invenção se refere ao sistema e método para melhorar o efeito do equipamento do usuário do fechamento interno (close-in) até um ponto onde o próprio equipamento do usuário limita o desempenho. o sistema e o método utilizam um filtro digital na frente do modulador laser sendo aplicado ao laser. adicionalmente, os detectores de potência total podem ser utilizados na entrada para evitar que os sinais indesejados sobrecarreguem as fases na frente do laser. nas direções de ligações ascendente e descendente, a filtragem digital bidirecional nas rus permite o uso seletivo de um determinado ru em uma determinada sub-banda, por um determinado wsp. o uso de filtragem digital no ru reduz a necessidade de comutação do hardware rf na extremidade da cabeça para conseguir o mesmo objetivo de flexibilidade de sinal, por um dos mais wsps, fornecendo um ou mais setores existentes dentro do das. 1/1
