A Detection Method of Time Slot Power Based on ARM Platform

Abstract

In order to effectively detect the time slot power of the repeater station and the base station which the mobile communication system of time division multiple access (TDMA) communication systems, In this paper, a signal acquisition hardware circuit based on ARM platform is designed, and a method of synthetically calculating time slot power is proposed. The signal acquisition circuit used an 8 channel ADC108 chip connected to ARM through the SPI bus, the time slot power detection method is composed of signal timing acquisition module, data acquisition module and data processing module to calculate the time slot power. And the validity of the method in detecting the time slot power under the condition of system boot and normal operation is tested, the system CPU resource consumption, the error value of the tested time slot power are tested also. The results show that the proposed method can effectively detect and control time slot power of TDMA system, and it has important significance to the repeater station and the base station system network signal coverage and optimization.
