摘要： There is disclosed a radio communication system in which a constitution of a base station and further a control station can be simplified. A radio communication system according to the present invention converts a received signal received by a plurality of antenna elements in a base station to a signal of different frequency band, and then conflates the converted signal in order to generate sub-carrier wave multiplex signal. The signal is converted to an optical signal, and then the optical signal is transmitted to a control station via an optical fiber. Or the control station performs weighting to phase of the transmitted signal transmitted from a plurality of antennas of a base station, and then performs frequency conversion to different frequency band, and then conflates the converted signal in order to generate the sub-carrier wave multiplex signal. The signal is converted to an optical signal, and then an optical signal is transmitted to the base station side via the optical fiber. The control station and the base station divides the received sub-carrier wave multiplex signal by each frequency band, and then the frequency of the divided signals are converted to the same frequency band in order to generate the transmitted/received signal of each antenna element. By such a constitution, it is possible to reduce constituent of the optical transmission components to the minimum and to simplify the constitution of the base station. Furthermore, it is possible to maintain the relative phase difference and the relative intensity of the transmitted/received signal of each antenna element. Because of this, it is possible to estimate an arrival direction of the received signal and to control radiation beam pattern of the transmitted signal.
摘要翻译：公开了一种无线电通信系统，其中可以简化基站的结构和控制站的结构。根据本发明的无线电通信系统将由基站中的多个天线元件接收的接收信号转换为不同频带的信号，然后混合转换的信号以产生副载波复用信号。信号被转换为光信号，然后光信号通过光纤传输到控制站。或者控制站对从基站的多个天线发送的发送信号的相位进行加权，然后对不同的频带进行频率转换，然后混合转换的信号，以产生副载波复用信号。信号被转换为光信号，然后经由光纤将光信号发送到基站侧。控制站和基站将接收到的副载波复用信号除以每个频带，然后将分频信号的频率转换为相同的频带，以便产生每个天线单元的发送/接收信号。通过这样的结构，能够将光传输部件的成分最小化，并且简化基站的结构。此外，可以保持每个天线元件的发送/接收信号的相对相位差和相对强度。因此，可以估计接收信号的到达方向并控制发送信号的辐射束图案。
