摘要： Methods and apparatus are disclosed for manufacturing antennas (100) with a unique signature and for identifying an antenna (100) using its unique signature. An exemplary antenna comprises a radiating element (104) and a ground element (102), between which a resistor-inductor-capacitor (RLC) circuit (106) is connected. The RLC circuit (106) is designed to generate a return-loss profile that serves as a unique antenna signature. The return-loss profile of the RLC circuit (106) exhibits a resonance frequency outside the antenna's working bandwidth.

摘要： The present invention provides methods and apparatus to detect the presence of interferers in a wideband digital VSWR measurement signal. Interferers cause power differences over different intervals of time and frequency, and may be detected by comparing the measured signals in both time and frequency domains with the original signal. Frequency components in the measured signals may be discarded if the interference is deemed too large. The remaining frequency components can then be used to compute the VSWR.

摘要： The present disclosure provides a method and device for detecting and repairing a channel anomaly of an active antenna, and the method includes: an operation state of a transmission channel or a reception channel is determined by analyzing in real time data of a feedback coupling channel or data of the reception channel, if the operation state is anomalous, an anomaly protection is performed and an alarm is reported; a level of the alarm and a reason causing the alarm are determined, if data of the transmission/reception channel are anomalous and the anomaly protection is performed, a current antenna beam forming parameter is stored and the antenna beam forming parameter is set to zero; after the alarm has been eliminated, a stored valid antenna beam forming parameter is set to a valid value; and if a transmission/reception analog channel operates anomalously and the anomaly protection is performed, the antenna beam forming parameter is re-acquired and an acquired valid antenna beam forming parameter is configured. The present disclosure can detect states of multiple transmission/reception channels of an active antenna without an extra calibration channel, thus reducing the design cost of a system.

摘要： Radio frequency energy deposition analysis can include receiving information defining one or more radio frequency sources. Information defining one or more objects interacting with energy from the radio frequency sources may also be received. Ray traces of radio frequency energy from the radio frequency source to the object may be calculated. Ray traces of radio frequency energy reflected off of the object can also be calculated. Finally, the radio frequency energy deposited onto the object from the ray traces can be determined. The deposited energy may be graphically displayed and queried.

摘要： The invention relates to a method for measuring the condition of a receiving antenna of a base station in a TDMA radio system, in which TDMA channel structures according to ETSI/GSM recommendation 05.02 are used, by means of test measurements performed in predetermined TDMA time slots. According to the invention, the test measurements are performed, without disturbing the normal operation of the base station and without allocating a traffic channel, during time slots of an IDLE frame of a channel structure TCH/F+SACCH/TF and/or during time slots of an IDLE frame of a channel structure SDCCH/8 according to the ETSI/GSM recommendation 05.02.

摘要： Base Station Transceiver Equipment (10) is provided such as for use in a cellular radio telephone system (fig. 3). A receiver (32) associated with a first base station transmitter in a first cell has means for monitoring a parameter of transmissions from a second base station transmitter (34-38) remotely located from the first base station transmitter. The receiver further comprises means for reporting, to a central management centre (40) responsible for the operational control of base stations (32-28) in the cellular radio communications system, if a change in said parameter is detected. The operation management centre (40) has means for determining whether the reported change in said parameter is due to a fault in the second base station transmitter and not to a specific operational change anticipated by the operation management centre.
