Abstract

The invention discloses an encryption transmission method of a 5G array antenna. And the adopted array antennas are arranged in a sparse array manner, so that the deployment cost is effectively reduced. Transmission information is split into small segments of signals, different encryption modes are selected for encryption according to error correction codes, and encrypted signals and timestamps are integrated to form encrypted signals. After the antenna receives the encrypted signal, whether the signal is interfered is judged through the timestamp and the error correction code, and then the signal is decoded by selecting the first decoding mode or the second decoding mode according to the position of the error correction serial number, so that the safety of signal transmission is ensured.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an encrypted transmission method for 5G array antennas. Background technique [0002] Antennas are widely used in radio systems such as communications, broadcasting, television, radar, and navigation. They play the role of spreading radio waves and are an essential device for effectively radiating and receiving radio waves. An array antenna is a special antenna that is arranged regularly or randomly by no less than two antenna elements and obtains predetermined radiation characteristics through proper excitation. The current rapid development of antenna communication knowledge and technology, as well as the proposal of many antenna research directions in the world, have prompted the birth of new antennas. Array antenna is a direction of research. The so-called array antenna is not simply arranging the antennas into an array that we are familiar with, but its composition is in the form of...
