The system comprises a set of M pickup sensors, a beam forming network coupled to the M pickup sensors, and a set of N injectors coupled to the beam forming network. The M pickup sensors pick up undesired signals in real time and generate M pickup signals, M being an integer greater than or equal to 1. The beam forming network comprises a set of M beam forming modules. Each of the M beam forming modules receives a respective one of the M pickup signals and generates N intermediate signals, N being an integer greater than 1. The N intermediate signals generated by each of the M beam forming modules are combined correspondingly with remaining intermediate signals generated by remaining M−1 beam forming modules to generate N interference signals. The N injectors receive and radiate the N interference signals to the target zone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Generating quiet zone by noise cancellation via injection techniques","description":"A system for reducing undesired interference in a target zone is disclosed.
