Method and device for obtaining timeslot power

Abstract

The invention provides a method and a device for obtaining timeslot power. The method for obtaining timeslot power comprises the following steps of: sampling the coupling power voltage value of a timeslot signal to be detected in an interval in which the power change of the signal is less than a threshold, to obtain a first detection value; and obtaining the timeslot power of the signal to be detected according to the corresponding relationship between the detection value of the timeslot signal and the timeslot power and the first detection value. In the embodiment of the invention, as the signal to be detected is sampled in an interval in which the power change is less than a threshold value, and the sampling points are significantly reduced. In the invention, not only the fast changing power of signal is sampled to obtain the timeslot power, but also the dependency of the timeslot power obtaining method on the performance of an ADC device is greatly reduced without a high-speed ADC device; therefore, the invention maintains the low cost of the system and simplifies the process for obtaining timeslot power.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for obtaining time slot power. Background technique [0002] GSM (Global System for Mobile Communications, Global System for Mobile Communications) is a widely used digital mobile phone system. GSM uses a time-division multiple access mode, and data services or voice services are carried in units of time slots. [0003] When a base station transmits a signal to a UE (User Equipment, user equipment), it needs to control the transmit power of the base station itself, so as to ensure the quality of the signal transmitted to the UE. Therefore, in order to realize the dynamic control of the transmission power, the base station needs to detect the power of the time slot in real time. [0004] In actual operation, first of all, in the production equipment stage, the digital detection voltage value output by the ADC (Analog-to-Digital Converter, analo...
