Orthogonal Frequency Division Multiplexing OFDM is an exceptional case of Frequency Division Multiplexing. The dilemma of OFDM is its sensitivity to frequency offset between the transmitted and received carrier frequencies. This frequency offset establishes Inter Carrier Interference ICI Cancellation in the OFDM symbol.

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 ...
