Abstract

"MéTODO E SISTEMA PARA CORRIGIR UMA INTERFERêNCIA DE CANAL DE RECEPçãO DE CONTROLE DE LAçO ABERTO CDMA, E ESTAçãO BASE PARA ESTE SISTEMA". Em uma estação base para um sistema de correção de interferência de canal de recepção de controle de laço aberto para realizar correção de interferência de canal de recepção, um receptor base recebe um sinal de transmissão reverso como sinal de transmissão recebido e mede as potências recebidas do sinal reverso recebido para produzir valores medidos de potência recebida. Uma seção de cálculo de potência média calcula uma média dos valores medidos de potência recebida para produzir um valor médio calculado. Com base no valor médio calculado e em um valor de referência, uma seção de cálculo de valor de correção calcula o valor de correção para fazer uma estação móvel aumentar a potência de transmissão corrente de modo a torná-la maior que a potência de transmissão prévia. Uma seção de transmissão transmite a informação indicativa do valor de correção para a estação móvel.
