Abstract

Presented herein are techniques that enable a PHY-level state machine to stitch together PPDUs, in real-time, in a network sensor that is resource constrained including limitation on the receiver decoding capacity. In a software-defined receiver for any incoming frame, a modified PHY state machine is employed to track MU-RTS/CTS, 802.11ax trigger frames, and other 802.11ax traffic to infer the source and destination of the undecodable packets. The modified PHY state machine further captures and ties PHY parameters into the receiver (Rx) path.
