The detection logic is configured to detect a signal containing a block of samples that includes a narrowband interferer from a communication channel. The offset generation logic is configured to align a frequency of the narrowband interferer to a center of a subcarrier frequency of the communication channel to produce an offset signal thereby introducing inter-carrier interference (ICI). The tone erasure logic is configured to remove the subcarrier frequency from the offset signal to produce an interferer erased offset signal. The correction generation logic is configured to remove the ICI to produce an interferer erased signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for improving narrowband interference performance","description":"An orthogonal frequency division multiplexing (OFDM) receiver includes detection logic, offset generation logic, tone erasure logic, and correction generation logic.
