Artificial Noise Injection

Technical Explanation

To guarantee that unauthorized eavesdroppers cannot intercept communications, 6G base stations transmit Artificial Noise (AN) simultaneously with user data. Utilizing the null-space of the authorized user's channel matrix, the base station projects high-power pseudo-random jamming noise into every spatial direction in the cell. The authorized user experiences zero noise (because the beam is mathematically orthogonal to their channel), while all eavesdroppers are completely blinded by noise.

Key Functions

• Projecting deliberate RF jamming noise into the null-space of the legitimate user's channel
• Authorized receiver experiences zero interference due to orthogonal spatial beam alignment
• Blinding unauthorized eavesdroppers across all surrounding angles with artificial noise
• Dynamically allocating transmit power between user data payload and jamming protection
• Physical layer protection preventing passive eavesdropping in public outdoor spaces
