Abstract

"ESTAçãO BASE PARA COMUNICAçãO COM PELO MENOS UMA ESTAçãO MóVEL EM UM SISTEMA DE COMUNICAçõES CELULAR E PROCESSO PARA OPERAR UMA ESTAçãO BASE CELULAR". Uma estação base inclui primeiro e segundo sistemas de antena para receber primeira e segunda polarizações circulares, e um receptor de diversidade de polarização conectado com os primeiro e segundo sistemas de antena para processar respectivos primeiro e segundo sinais de recepção de uma estação móvel para gerar um sinal de recepção de saída de qualidade aumentada baseado sobre recepção de diversidade de polarização. O isolamento de polarização entre os elementos de antena de transmissão e de recepção também pode ser proporcionado tendo-se uma primeira pluralidade de elementos de antena de transmissão para a segunda polarização montados sobre um substrato portador dos primeiros elementos de antena de recepção. O segundo sistema de antena inclui uma segunda pluralidade de elementos de antena de segunda polarização sobre um substrato portador dos segundos elementos de antena de recepção. Para obter ganho de diversidade de polarização na estação móvel, a estação base de preferência inclui adicionalmente um transmissor de polarização alternada para alternadamente transmitir sinais em respectivas primeira e segunda polarizações circulares alternadas. Aspectos do processo da invenção são também expostos.
