摘要：
Signal reception apparatus comprising at least two antennas, receiver means having a first mode of operation for assessing the quality of received signals and a second mode of operation for processing received signals for identifying data carried therein, at least two signal paths connectable between the antennas and the receiver means and each capable of demodulating signals received by the antennas and switch means connected between the antennas and the signal paths, the apparatus having an assessment mode of operation in which each antenna is connected by the switch means to the receiver means via a single respective one of the signal paths and in which the receiver means operates in its first mode of operation to assess the quality of received signals from each antenna, and a normal mode of operation in which a single antenna is connected by the switch means to the receiver means via all of the signal paths and in which the receiver means operates in its second mode of operation for processing received signals for identifying data carried therein.
摘要（中）：
包括至少两个天线的信号接收装置，具有用于评估接收信号的质量的第一操作模式的接收器装置和用于处理用于识别其中携带的数据的接收信号的第二操作模式，至少 两条信号路径可连接在天线和接收器装置之间，并且每条信号路径能够解调由天线接收的信号和连接在天线和信号路径之间的开关装置，该装置具有评估操作模式，其中每个天线通过开关 通过信号路径中的单个相应信号路径到接收机装置的装置，其中接收机装置在其第一操作模式下操作以评估来自每个天线的接收信号的质量，以及其中单个天线是正常操作模式 通过所有的信号路径由开关装置连接到接收装置，并且接收装置在第二模式中操作 f操作，用于处理接收到的信号以识别其中携带的数据。
