Systems and methods for detecting beam-formed orthogonal frequency division multiplexing (OFDM) packets

A system for detecting beam-formed orthogonal frequency division multiplexing (OFDM) packets to determine a data symbol processing procedure in response to a beam-formed packet, the system comprising:

• a wireless receiver configured to receive a data signal including a data packet;
• a channel estimation module configured to select a set of frequency domain tones associated with the data signal;
• and
• a jump counting module configured to:
• calculate a plurality of differential parameters between adjacent frequency domain tones from the set of frequency domain tones,
• identify a jump when a first differential parameter from the plurality of differential parameters exceeds a jump threshold,
• obtain an accumulative count of jumps for the set of frequency domain tones, and
• identify the data packet is beam-formed when the accumulative count exceeds a jump limit;
• and
• a data symbol processing module to select a data symbol processing procedure to decode the data packet based on whether the data packet is beam-formed.
