TD-SCDMA/TD-LTE downlink shielding device and design method thereof

Abstract

The invention discloses a TD-SCDMA / TD-LTE downlink shielding device and a design method thereof, and belongs to the field of mobile communications. The shielding device comprises a receiving unit, a synchronizing signal conversion unit, a synchronizing signal analysis unit, an interference signal generating unit, an interference signal enhancing unit, a gain adjusting unit, a digital control center, a monitoring unit and an emitting unit, wherein the receiving unit, the synchronizing signal conversion unit and the synchronizing signal analysis unit are connected in sequence; the synchronizing signal analysis unit, the monitoring unit, the interference signal generating unit and the gain adjusting unit are all connected with the digital control center; and the interference signal generating unit, the interference signal enhancing unit and the emitting unit are connected in sequence. The invention further discloses a design method of the TD-SCDMA / TD-LTE downlink shielding device. The shielding device and the design method make the best of time slot characteristics of the TD-SCDMA / TD-LTE network to interfere for different time slots, interfere in the downlink time slot, and avoid the condition that the interference from the downlink shielding device in the uplink signal of a base station results in influencing the normal operation of the base station, and the downlink interference signal strength is controllable, and the interference range is controllable.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a TD-SCDMA / TD-LTE downlink shielding device and a shielding method. Background technique [0002] In today's information age, the development of communication technology is changing with each passing day. Mobile communication, as a unique branch of the communication family, plays an important role in people's life and in various fields such as industrial and agricultural production. However, mobile phones are bringing great convenience to people's lives. At the same time, there are also some problems that cannot be ignored. Due to the wide coverage of the mobile communication network, in some occasions the emergence of the network, the use of mobile phones has brought troubles to people, and even hidden safety hazards, such as: (1) becoming a new channel for leaking secrets, posing a threat to the security of confidential information; ( 2) It becomes a new source ...

AI Technical Summary

Problems solved by technology

[0004] In the TD-SCDMA / TD-LTE communication system, the current terminal signal jammer interferes with the network signal of a specific frequency band, without time-slot interference, the user cannot receive the signal and cannot call out at the same time, and the strength of the interference signal is fixed, the interference inconvenient control of the range
