Embodiment Construction

[0051] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0052] 1. Jammer

[0053] 1. Overall

[0054] like figure 1 , the jammer includes an antenna 10, a signal processor 20, and a power supply 30; the signal processor 20 includes a radio frequency processing module 21 and a baseband processing module 22 that interact with each other;

[0055] The antenna 10 is connected to the signal processor 20 , and the power supply 30 is connected to the signal processor 20 .

[0056] Working mechanism:

[0057] After the jammer is powered on, the 5G downlink signal is received through the antenna 10 and sent to the radio frequency processing module 21. The radio frequency processing module 21 amplifies, analog-to-digital conversion (A / D) and down-converts the radio frequency signal received by the antenna to obtain the baseband The IQ data is sent to the baseband processing module 22;

[0058] After the baseband processing module 22 demodulates th...

Abstract

The invention discloses a 5G green wireless signal shielding device and a shielding method thereof, and relates to the field of 5G mobile communication. The shielding device is characterized in that an antenna is connected with a signal processor, and a power supply is connected with the signal processor, the signal processor comprises a radio frequency processing module and a baseband processingmodule which interact with each other. The shielding method comprises the following steps: 1, searching cells; 2, solving MIB / SIB; 3, generating a PSS interference sequence; 4, generating an SSS interference sequence; 5, generating a PBCH DMRS interference sequence; 6, performing resource mapping; and 7, generating an OFDM baseband signal. The invention has the following advantages and positive effects: (1) the intensity of an interference signal generated by the shielding device only needs to be 3 dB greater than the signal intensity of a 5G public network, so that the signal shielding can be completely realized; 2, 5G uplink signals are not interfered, and the base station is not influenced; and 3, the transmitted interference signal only occupies a small amount of time-frequency resources, so that the power of the shielding device can be greatly reduced, and environmental protection and high efficiency are achieved.

Description

technical field [0001] The invention relates to the field of 5G mobile communications, in particular to a shielding device for 5G green wireless signals and a shielding method thereof. Background technique [0002] At present, with the rapid development of mobile communication technology, the fifth generation of mobile communication technology is coming to us at a fast pace. 5G mobile communication network has the characteristics of ultra-large bandwidth, low latency and high security, and will become the main mobile communication network after 2020. However, while the 5G mobile network brings convenience to people's lives, it will also cause some problems that cannot be ignored. For example, in some occasions, the use of 5G mobile network will bring troubles to people, and even pose a safety hazard. In this case, 5G wireless signal jammers came into being. In the era of 5G Internet of Everything, the traditional wireless signal shielding scheme can no longer meet the sign...
