The method includes receiving, at a receiver, a data signal including a data packet, and selecting a set of frequency domain tones associated with the data signal for channel estimation. The method further includes calculating a plurality of differential parameters between adjacent frequency domain tones from the set of frequency domain tones. The method further includes identifying a jump when a first differential parameter from the plurality of differential parameters exceeds a jump threshold. The method further includes obtaining an accumulative count of jumps for the set of frequency domain tones, and identifying the data packet is beamformed when the accumulative count exceeds a jump limit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for detecting beam-formed orthogonal frequency division multiplexing (OFDM) packets","description":"Systems and methods described herein provide a method for detecting beamformed detecting beam-formed orthogonal frequency division multiplexing (OFDM) packets.
