Orthogonal frequency division multiplexing (OFDM) is a widely used modern communications technology due to its resistance to selective frequency fading and efficient use of spectrum. However, the security of OFDM signals remains a source of serious concern, especially in the face of network encryption that aims to disrupt communications or extract ...
