Problems solved by technology

However, if the frame headers of the TD-LTE system between multiple frequency bands are not synchronized, it will be difficult to track the jammer synchronously, because the jammer needs to scan back and forth between multiple frequency bands in order to track the synchronous multiple channels at the same time. TD-LTE system on frequency bands

Abstract

The invention discloses a synchronization method in an interference unit. The method comprises: a synchronization signal on a reference frequency band is tracked and a current frame head position of the reference frequency band is obtained; according to a time difference of a frame head position of a communication system supported by the interference unit at each frequency band and the frame head position of the reference frequency band as well as a current frame head position of the reference frequency band, a current frame head position of each frequency band is determined; a frame structure of each frequency band is obtained; and on the basis of the current frame head position of each frequency band and a corresponding frame structure, a synchronous control signal is sent, wherein the synchronous control signal is used for controlling a transmitting link in the interference unit to transmit an interference signal. In addition, the invention also discloses a synchronization apparatus in an interference unit and an interference unit.

Description

technical field [0001] The invention relates to jammer technology, in particular to a synchronization method and device in a jammer, and a jammer. Background technique [0002] In some sensitive places such as party and government organs or school examination rooms, for purposes such as confidentiality, it is necessary to block normal mobile phone communications in specific areas or places. In this case, jammers are generally deployed near the target area. figure 1 It is a schematic diagram of the network architecture in the prior art, such as figure 1 As shown, generally speaking, the jammer 11 is a high-power wireless signal transmitter, and the jammer 11 continuously transmits high-power interference or noise signals on the same downlink frequency as the base station 12 . Therefore, the user equipment (UE) 13 in the target area 13 will also be strongly interfered by the interferer 11 while receiving normal base station signals, thereby causing the UE 13 to be unable to m...
