The digital television signal is correlated to a reference digital television field sync signal. A non-coherent correlation power measurement is determined based on the correlation of the received digital television signal to the reference digital television field sync signal. A plurality of maximum non-coherent correlation power measurements are determined over multiple field times. An energy estimate for the digital television transmission is determined based on the maximum non-coherent correlation power measurements. A transmit mask filter is generated based on the energy estimate. The transmit mask is applied to transmissions to reduce interference with detected digital television transmissions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spectrum sensing engine","description":"Systems, methods, and devices for reducing interference with digital television transmissions occurring over a bandwidth are disclosed.
