Abstract

"CONTROLE DE TRANSMISSãO DE SINAL CDMA". A invenção consiste de uma tecnologia de controle de transmissão CDMA (600) que inclui várias combinações das seguintes funcionalidades: eliminação de cristas ("decresting"), razão em banda para fora de banda (RIO) (611), controle de potência e formatação espectral (614). A eliminação de cristas reduz picos no sinal CDMA. A RIO (612) gera uma razão com base na força de sinal de porções em banda contra fora de banda do sinal CDMA. O controle de potência ajusta o ganho do sinal CDMA com base em cálculos de quadratura de sinais. A formatação espectral atenua porções em banda do sinal CDMA adjacentes às freq³ências de quina (corner frequencies). A tecnologia de controle de transmissão CDMA pode ser implementada em uma estação base CDMA para aumentar o alcance e a capacidade.
