Abstract

The invention discloses a simulation test terminal and a signal processing method. The simulation test terminal comprises a signal search module, a time base calibration module and a signal transmitting module. The signal search module is used for searching for a time division wireless signal of the cell where the simulation test terminal is located. The time base calibration module is used for determining the time base of the cell where the simulation test terminal is located according to the time division wireless signal found by the signal search module and conducting signal transmitting time base calibration on the simulation test terminal according to the signal time base. The signal transmitting module is used for transmitting the time division wireless signal according to the signal transmitting time base which is calibrated by the time base calibration module. According to the simulation test terminal and the signal processing method, when finding the time division wireless signal of the cell where the simulation test terminal is located, the simulation test terminal can conduct transmission time base calibration according to the time division wireless signal and then achieve signal synchronization, so that the problem that in the prior art, an indoor simulation signal source cannot achieve accurate synchronization with an existing time division communication system is solved, and the effect of signal synchronization is improved.

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), Time Division Long Term Evolution (Time Division-Long Term Evolution, TD-LTE), because the time division communication The various cells in the system need to be strictly synchronized with each other, so as to avoid the problem of mutual inte...
