A device and method for detecting signal power supporting multiple communication systems

Abstract

The invention relates to a method and a device supporting power detection of signals of various communication systems. The method comprises the following steps of acquiring a power signal of each radio remote unit; judging whether a current service signal access state type is a single-service signal or a multi-service signal; and respectively computing sampling voltage corresponding to the servicesignal at the moment according to different service signal access state types, and then computing a corresponding port actual power value according to a corresponding relation between the voltage andthe power generated by the earlier-stage calibration. According to the method and the device, real-time power detection can be carried out on input and output ports of the communication signals of multiple systems. A problem that an output antenna feeder terminal of communication base station equipment is difficult to accurately detect the power due to the fact that the components of a compositesignal obtained after combination of the signals of different systems and different frequency bands of the base stations of multiple operators is solved, and the method and the device can be applied to accurate measurement of the power of the composite signal obtained after combination of multiple paths of signals of different systems, different frequency bands and different power.

AI Technical Summary

Problems solved by technology

The main problems faced are: time-division and frequency-division signal systems are different, the waveforms of the signals after detection are different, it is difficult to separate the signals of different systems and calculate their power; when the power of different input port signals is different at the same time, the antenna feeder The level signal after the mixed signal detection at the end is difficult to distinguish between high and low; the signal components at the antenna and feeder end are complex, and the power detection accuracy is not high

However, since the TD-SCDMA and TD-LTE two standard cells send different signals, it is difficult to accurately detect the output power when the feeder signal contains two standard signals at the same time.

A variety of business signals of different standards, different frequency bands, and different powers are combined and mixed, and the signal components are complex, and the accuracy of power detection is not high.

Similarly, when the day feeder service signal includes both time-division multiplexing and frequency-division multiplexing, it is even more difficult to accurately detect its output power.
