Abstract

The invention discloses a simulation test terminal and a signal processing method. The simulation test terminal includes: a signal search module for searching time-division wireless signals in the cell where the simulation test terminal is located; a time base calibration module for searching The time-division wireless signal searched by the module determines the signal time base of the cell where the simulated test terminal is located, and performs the signal transmission time base calibration of the simulated test terminal according to the signal time base; The signal transmission time base calibrated by the time base calibration module is used to transmit time-division wireless signals. In this solution, when the analog test terminal searches for the time-division wireless signal of the cell, it can calibrate the transmission time base according to the signal time base of the time-division wireless signal, and then realize signal synchronization, thus solving the problem existing in the prior art The problem that the indoor analog signal source cannot achieve precise synchronization with the existing time division communication system improves the effect of signal synchronization.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an analog test terminal and a signal processing method applicable to a time division communication system. Background technique [0002] At present, when constructing a wireless communication network, in order to determine the best base station location, it is usually necessary to carry out a simulation test, that is, to deploy an analog signal source at a set candidate position, and to traverse the surrounding paths of the analog signal source way to test the coverage of wireless signals. [0003] Specifically, for time-division communication systems such as Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) and Time Division-Long Term Evolution (TD-LTE), since the time-division communication system Each cell in the network needs to be strictly synchronized with each other, so as to avoid the problem of mutual interference between cells. Therefore...
