Abstract

"MéTODO PARA DETERMINAR OS GANHOS DE RADIOFREQuêNCIA SEPARADOS PARA PORTADORAS DIFERENTES EM UM TRANSMISSOR DE MULTI-PORTADORA DE UMA UNIDADE DE RADIOTRANSMISSãO DE UM SISTEMA DE RADIOCOMUNICAçãO, USO DE UM MéTODO, UNIDADE DE RADIOTRANSMISSãO PARA UMA REDE DE RADIOCOMUNICAçãO, MóDULO PARA UMA UNIDADE DE RADIOTRANSMISSãO DE UM SISTEMA DE RADIOCOMUNICAçãO, E, REDE DE RADIOCOMUNICAçãO". A invenção relaciona-se a métodos para determinar os ganhos de radiofreq³ência separados para portadoras em um transmissor de multi-portadora de uma unidade de radiotransmissão de um sistema de radiocomunicação. Para habilitar uma estimação simples e precisa dos ganhos, é proposto determinar os ganhos individuais (G~ 1~-G~ N~) das portadoras diferentes matematicamente de conjuntos diferentes de potências (REF~ 1~REF~ N~) em algum ponto em cada unidade de portadora única e as potências de saída totais correspondentes do transmissor. Alternativamente, a relação das potências das portadoras diferentes entre si é determinada logo antes que as portadoras sejam combinadas a um único sinal de multi-portadora. Esta relação é usada para determinar a contribuição das portadoras diferentes à potência de transmissão do sinal de multi-portadora e para dela determinar os ganhos de radiofreq³ência para as portadoras diferentes. A invenção relaciona-se igualmente a unidades de radiotransmissão correspondentes e módulos de tais unidades de radiotransmissão.
