Abstract

SISTEMA DE ANTENA E TRANSMISSOR COMPENSADO COM PRÉ-DISTORÇÃO E MÉTODO PARA PROPORCIONAR DE UMA MANEIRA ADAPTATIVA UM FEIXE DE ANTENA DE UM SISTEMA DE ANTENA E TRANSMISSOR. A presente invenção refere-se a um sistema e um método de comunicação aperfeiçoado empregando uma arquitetura de antena com uma disposição de elementos em uma ou mais dimensões controlada. A disposição com elementos em uma ou mais dimensões (10) contém uma pluralidade de elementos de irradiação operados que são espacialmente arranjados tendo um par de elementos de irradiação (112, 114) alimentados com um sinal de RF Pprédistorcido de tal maneira para proporcionar uma variação controlada do padrão de irradiação de elevação da antena com uma disposição de elementos em uma ou mais dimensões. A eficiência do amplificador de alta potência (PA = Power Amplifier/Public Addressing) é mantida por meio de pré-distorção adaptativa acoplada a cada um dos PA (140, 142), enquanto é proporcionado um controle de inclinação de feixe e irradiação lateral.
