摘要： PROBLEM TO BE SOLVED: To accurately capture unknown radio waves to be monitored and efficiently measure their arrival direction. SOLUTION: By detecting, for example, the frequency of a signal received by a reception antenna 1 and comparing it with a preset frequency, it is determined by a determining part 3 whether it is a reception signal of an object to be monitored. When the determining part 3 determines that it is of the object to be monitored, a command 3b to measure their arrival bearing in addition to radio wave (frequency) data 3a on the reception signal is supplied for an arbitration part 4. Since the arbitration part 4 appropriately selects bearing measuring parts 5 (51-5N) for measuring the arrival bearing from among the plurality of bering measuring parts 5 (51-5N), and supplies the radio wave (frequency) data 3a and the bearing measurement command 3b, the arbitrary part 4 supplies a monitoring table 6 with the result (5a) of bearing measurement measured by the bering measuring parts 5 (51-5N). Therefore, the monitoring table estimates the bearing or location of a transmission source of the radio waves to be monitored and displays it on a map. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a radio wave monitoring apparatus for efficiently measuring an arrival direction of an unknown radio wave by surely acquiring the unknown radio wave being a monitor object. SOLUTION: A discrimination section 3 analyzes e.g., a frequency of a signal received by a reception antenna 1 and compares the frequency with a preset frequency to discriminate whether or not the signal is a received signal from a monitor object. When the discrimination section 3 discriminates the signal to be the signal of the monitor object, the discrimination section 3 supplies an arrival azimuth measurement command to an arbitration section 4 together with radio wave item data (frequency) of the received signal. The arbitration section 4 properly selects any of azimuth measurement sections 5 (51 to 5N) to measure the radio wave arrival azimuth among the plurality of azimuth measurement sections 5 (51 to 5N) and supplies the radio wave item data (frequency) and the azimuth measurement command to the selected azimuth measurement section. Thus, the arbitration section 4 receives the azimuth measurement result measured by any of the azimuth measurement sections 5 (51 to 5N) and supplies the result to a monitor console 6, which can estimate the azimuth or position of a transmission source and perform display or the like.

摘要： PROBLEM TO BE SOLVED: To receive normal data from an arbitrary transmission data stream in a short period of time even without knowing in advance a parameter required for a receiver terminal to receive each of transmission data streams.
SOLUTION: Parameter information such as the encoding rate of convolution codes in each transmission data stream and an interleaving size is time division-multiplexed in a synchronizing signal while being spread with the same synchronization spreading code as a spreading code used for a synchronizing process of the spreading code. Therefore, as long as the synchronizing signal is being received, the parameter information is acquired regardless of the reception of each transmission data stream. Parameters for the respective parts of a receiver are set on the basis of the parameter information of transmission data streams acquired by receiving the synchronizing signal, thereby easily and speedily performing the receiving process of transmission data streams.

摘要翻译：要解决的问题：即使在事先不知道接收机终端接收每个发送数据流所需的参数的情况下，也可以在短时间内从任意发送数据流接收正常数据。解决方案：在同步信号中对诸如每个传输数据流中的卷积码的编码率和交织大小的参数信息进行时分复用，同时以与用于同步的扩展码相同的同步扩展码进行扩展扩展码的处理。因此，只要正在接收同步信号，就获取参数信息而不管每个传输数据流的接收。基于通过接收同步信号获取的发送数据流的参数信息来设置接收机的各个部分的参数，从而容易且快速地执行发送数据流的接收处理。版权所有（C）2005，JPO＆NCIPI
