Abstract

Patente de Invenção: <B>"ESTAçãO DE BASE DE RáDIO MóVEL COM ANTENA ADAPTáVEL"<D>. Uma estação de base de rádio móvel, com um transmissor (TRX) para cada freq³ência de transmissão, bem como com vários receptores (RX 1, RX 2, RX 3, RX 0), sendo que as saídas de antenas individuais (AN 1, AN 2, AN 3) ou de uma rede de matriz (BUM), bem como de pelo menos uma antena onidirecional (AN 0), estão unidos com desvios de transmissão/recepção (SE 1, SE 2, SE 3, SE 0) e os ramais de recepção dos desvios estão guiados para os receptores individuais (RX 1, RX 2, RX 3, RX 0), os ramais de transmissão dos desvios estão unidos seletivamente, através de um dispositivo de ligação (SWI) controlado, com a saída de um transmissor (TRX) e, para processamento dos sinais de saída do receptor, está previsto um detector (DET) comum, que está configurado para fornecer, através de um comando de antena (AST), ao dispositivo de ligação um sinal de comando (stw) de um tipo tal que o transmissor seja unido com uma antena determinada no detector (DET).Invention Patent: <B> "MOBILE RADIO BASE STATION WITH ADAPTABLE ANTENNA" <D>. A mobile radio base station, with a transmitter (TRX) for each transmission frequency, as well as several receivers (RX 1, RX 2, RX 3, RX 0), with individual antenna outputs (AN 1, AN 2, AN 3) or a matrix network (BUM), as well as at least one omnidirectional antenna (AN 0), are linked with transmission / reception deviations (SE 1, SE 2, SE 3, SE 0) and the branches of reception of the diversions are guided to the individual receivers (RX 1, RX 2, RX 3, RX 0), the branches of transmission of the diversions are selectively united, through a controlled connection device (SWI), with the output of a transmitter (TRX) and, for processing the output signals of the receiver, a common detector (DET) is provided, which is configured to supply, through an antenna command (AST), to the connection device a signal of command (stw) of a type such that the transmitter is joined with an antenna determined in the detector (DET).
